Trivia: An icon of machismo and Hollywood action heroism, Sylvester Stallone is responsible for creating two characters who have become a part of the American cultural lexicon: Rocky Balboa, the no-name boxer who overcame all odds to become a champion, and John Rambo, the courageous soldier who specialized in violent rescues and revenge. Both characters are reflections of Stallone's personal experiences and the battles he waged during his transition from a poor kid in Hell's Kitchen to one of the world's most popular stars. According to Stallone, his was not a happy childhood. On July 6, 1946, in the aforementioned part of Manhattan, Sylvester Enzio Stallone was born to a chorine and an Italian immigrant. A forceps accident during his birth severed a facial nerve, leaving Stallone with parts of his lip, tongue, and chin paralyzed. In doing so, the accident imprinted Stallone with some of the most recognizable components of his persona: the distinctively slurred (and some say often nearly incomprehensible) speech patterns, drooping lower lip, and crooked left eye that have been eagerly seized upon by caricaturists. To compound these defects, Stallone was a homely, sickly child who once suffered from rickets. His parents were constantly at war and struggling to support Stallone and his younger brother, Frank Stallone (who became a B-movie actor). The elder brother spent most of his first five years in the care of foster homes. Stallone has said that his interest in acting came from his attempts to get attention and affection from those strangers who tried to raise him. When he was five, his parents moved their family to Silver Spring, MD, but once again spent their time bickering and largely ignored their children. Following his parents' divorce in 1957, the 11-year-old Stallone remained with his stern father. The actor's teen years proved even more traumatic. As Stallone seemed willing to do just about anything for attention, however negative, he had already been enrolled in 12 schools and expelled several times for his behavior problems. His grades were dreadful and his classmates picked on him for being different. Stallone coped by becoming a risk taker and developing elaborate fantasies in which he presented himself as a brave hero and champion of the underdog. At age 15, Stallone moved to Philadelphia to be with his mother and her new husband. By this time, he had begun lifting weights and took up fencing, football, and the discus. He also started appearing in school plays. Following graduation, Stallone received an athletic scholarship for the American College of Switzerland. While there he was a girls' athletic coach and in his spare time starred in a school production of Arthur Miller's Death of a Salesman. The experience inspired him to become an actor and after returning stateside, he started studying drama at the University of Miami until he decided to move to New York in 1969. While working a variety of odd jobs, Stallone auditioned frequently but only occasionally found stage work, most of which was off-Broadway in shows like the all-nude Score and Rain. He even resorted to appearing in the softcore porn film, Party at Kitty's and Studs, which was later repackaged as The Italian Stallion after Stallone became famous. Stallone's face and even his deep voice were factors in his constant rejection for stage and film roles. He did nab a bit role in Woody Allen's Bananas (1971), but after he was turned down for The Godfather (1971), Stallone became discouraged. Rather than give up, however, Stallone again developed a coping mechanism -- he turned to writing scripts, lots of scripts, some of which were produced. He still auditioned and landed a starring role in Rebel (1973). During his writing phase, he married actress Sasha Czack in late 1974 and they moved to California in the hopes of building acting careers. His first minor success came when he wrote the screenplay for and co-starred in the nostalgic Lords of Flatbush (1974) with Henry Winkler. The film's modest success resulted in Stallone's getting larger roles, but he still didn't attract much notice until he penned the screenplay for Rocky. The story was strong and well written and studios were eager to buy the rights, but Stallone stipulated that he would be the star and must receive a share of the profits. Producers Irwin Winkler and Robert Chartoff accepted Stallone's terms and Rocky (1976) went on to become one of the biggest movie hits of all time. It also won several Oscars including ones for Best Picture, Best Director for John Avildsen, and a Best Actor nomination for Stallone. Suddenly Stallone found himself on Hollywood's A-list, a status he has largely maintained over the years. In addition to writing four sequels to Rocky, he penned three Rambo films (First Blood, Rambo: First Blood Part II, and Rambo 3) and F.I.S.T. (1979). Stallone made his directorial debut with Paradise Alley, which he filmed in Hell's Kitchen. He also wrote and directed but did not appear in the sequel to Saturday Night Fever, Staying Alive (1983). In addition, Stallone has continued to appear in the films of other directors, notably Demolition Man (1993), Judge Dredd (1995), and Copland (1997), a film in which he allowed himself to gain 30 pounds in order to more accurately portray an aging sheriff. Occasionally, Stallone has ventured out of the action genre and into lighter fare with such embarrassing efforts as Stop! Or My Mom Will Shoot (1992) and Oscar (1991), which did not fare well at the box office. Following these missteps, Stallone found greater success with the animated adventure Antz (1998), a film in which his very distinctive voice, if not his very distinctive physique, was very much a part. Stallone was back in shape for the 2000 remake of Get Carter and hit the race tracks in the following year in the CART racing thriller Driven. Though the early 2000s found his career sputtering along with such forgettable duds as D-Tox and Avenging Angelo, Stallone took his career into his own hands by returning to the director's chair to resurrect two of his most iconic characters. Lacing his boxing gloves up once again for Rocky Balboa, the veteran action star proved he still had some fight left in him, and venturing into the jungles of Burma as John Rambo just two years later, he proved that hard "R" action could still sell in the era where most filmmakers were playing it "PG-13"safe. That trend continued with Stallone's all-star action opus The Expendables in 2010, with the success of that film leading to a sequel (with Simon West taking over directorial duties) featuring even more action icons in 2012. Incredibly, not even a broken neck suffered during production of The Expendables proved capable of slowing Stallone down, and 2013 found him teaming with Walter Hill for Bullet to the Head -- which followed a cop and a killer as they teamed up to take down a mutual enemy. In 2015, Stallone returned to Rocky Balboa once more, but this time as a supporting character in the spin-off film Creed. He earned rave reviews and an Oscar nomination for Best Supporting Actor, making him only the sixth performer to be nominated for playing the same character in two separate films.

Trivia: Actor and occasional producer Sung Kang launched his career in the early 2000s. Though he continually tackled bit parts or supporting roles that called for standard Asian types, such as guest spots on NYPD Blue and in features such as Antwone Fisher (2002) and Forbidden Warrior (2004), Kang made his most enduring mark by co-producing and starring in a series of critically praised independent films with predominantly Asian-American casts and crews. The first of these projects arose when Kang signed to associate produce and tackle a plum role as one of the leads in writer/director Justin Lin's drama Better Luck Tomorrow (2002), about a group of troubled Asian-American adolescents who drift ever so casually into low-level crime. He followed it up by producing and starring in a sophomore project, the action-infused crime saga Undoing (2006), as a somewhat naïve young man who embarks on a crusade of vengeance against the thugs who rubbed out his best friend. Additional supporting roles ensued, in features such as The Fast and The Furious: Tokyo Drift (2006), Live Free or Die Hard (2007), and War (2007).

Trivia: Though she qualifies as a direct descendant of Middle Eastern royalty -- the great-great-grandaughter, in fact, of a 19th century Persian shah -- Iranian-American Sarah Shahi lived out several offscreen roles exotic enough to rival anything in her lineage. During her adolescence, she enjoyed stints as a USO performer and Dallas Cowboys cheerleader, and graduated from that experience to a successful Hollywood acting career at the behest of Robert Altman, who advised her in 2000 to make a beeline for the West Coast and audition for television pilots. Heeding this advice, Shahi gained national attention a short time later, as Jenny during the first season of the spy series Alias (opposite Jennifer Garner), and -- following guest appearances on Dawson's Creek -- debuted cinematically with a small but memorable role as a (very) willing classroom participant, in the Will Ferrell/Vince Vaughn frat boy comedy Old School (2003). Alongside fleeting appearances in such movies as Legally Blonde 2 (2003) and For Your Consideration (2006), Shahi also played the regular role of Carmen de la Pica Morales on Showtime's lesbian-themed drama The L Word during that program's second and third seasons. After her run on that series, she appeared in the short-lived sitcom Teachers (2006), and then found another regular role the next year on the cop drama Life, playing Dani Reese, partner of main character Charlie Crews (Damian Lewis). Shahi would continue to appear in several other projects, including films like I Don't Know How She Does It and the TV series Fairly Legal. In 2013, she had a guest stint on Person of Interest, which turned into a series regular role.

Trivia: Grew up in London and Nigeria. Modeled in London and Milan before turning to acting (and after obtaining a master's degree in law); moved to the U.S. to pursue an acting career in 1994. Appeared in the music videos for EnVogue's "Giving Him Something He Can Feel" and Mary J. Blige's "Love No Limit." Nominated for NAACP Image Awards in the Best Supporting Actor: Drama Series category for his role in HBO's Oz in 1997 and 2000. The meaning of his name: "ade" (crown); "wale" (to come home); "akin" (warrior); "nuoye" (chief); "agbaje" (wealth, prosperity). Came up with the name of his Lost character, Mr. Eko, himself. Nickname is "Triple A."

Trivia: Hawaii-born Jason Momoa first caught the attention of the fashion industry when he was discovered by designer Takeo in 1999. The 20 year old began a modeling career, which he soon transformed into an acting career, appearing in Baywatch Hawaii and Stargate Atlantis. In 2009, Momoa took on a role in the thriller The Game, before joining the cast of the acclaimed period series Game of Thrones in 2011. That same year, Momoa took on the title role in a hard hitting remake of Conan the Barbarian. Even though Conan failed to conquer the box office, Momoa's career kept charging forward thanks to his involvement eith the hit Game of Thrones, and in 2012 the actor could be seen opposite action icon Sylvester Stallone in the gritty Walter Hill actioner Bullet to the Head.

Trivia: Born into a show business family -- father Michael Hawkins is a stage actor and mother Mary Jo Slater is a casting director -- Christian Slater made his acting debut at age eight after his mother cast him in the television soap opera One Life to Live on a lark. The following year Slater was on Broadway starring opposite Dick Van Dyke in The Music Man. Slater would remain on Broadway for at least two more productions. As a youth, Slater attended Manhattan's Professional Children's School. He made his television debut in the movie Living Proof: The Hank Williams Junior Story (1983) and his film debut two years later when he was only 16 in The Legend of Billy Jean. Slater earned some of his first favorable notice starring opposite Sean Connery in The Name of the Rose (1986). He next appeared in Tucker, a Man and His Dream (1988), and more films followed after that, but Slater did not become a star until he co-starred opposite Winona Ryder in the darkly satirical Heathers in which he played an anarchic sociopath. His maniacal over-the-top performance led to comparisons with Jack Nicholson. After Heathers, it looked as if Slater was destined to be typecast into playing lunatic villains or seriously troubled youths. In the latter regard, life seemed to mirror his art.In 1989, he was arrested in West Hollywood for leading the police on a drunken car chase that ended when Slater crashed his car into a telephone pole. While trying to escape the car, he kicked a cop with his cowboy boot and then attempted to flee over a fence. In 1994, he was arrested for taking a gun aboard a plane. In 1997, Slater was arrested for attacking his lover and biting a police officer in the belly while drinking heavily; he was sentenced to spend 90 days in a suburban jail in early 1998, all this just one day after his newest film, Hard Rain, premiered. Shortly after sentencing, Slater admitted that he had also been taking cocaine and heroin at the time. As part of his sentence, he had to serve post-jail time in a drug/alcohol rehab program and attend a year-long program on preventing domestic violence. Despite his personal struggles, Slater has maintained a film career starring as a high school geek with a cool secret life in Pump Up the Volume (1990) to the romantic Bed of Roses (1996) to high-voltage actioners like Broken Arrow (1996). In his 1997 production Julian Po, he gained weight, grew a mustache, and appeared as a suicidal bookkeeper who embezzles money from his company so he can fulfill one final wish. Though subsequent roles in such critically-panned films as 3000 Miles to Graceland, Windtalkers, and Alone in the Dark did little to advance Slater's career, recurring roles in such popular television series' as Aaron Sorkin's The West Wing and J.J. Abrams' Alias offered not only more exposure, but a chance to reestablish himself on the small screen as well. Meanwhile, a promising debut as a secret agent with a duel personality on NBC's My Own Worst Enemy proved a bit of a false start when the network never offered the show a chance to find its legs. Ever resiliant, Slater quicky bounced back with ABC's The Forgotten in 2009 and Fox's Breaking In in 2011, though neither series failed to catch on, leaving the veteran actor to take up arms as a vengeful gunslinger in the 2012 western Dawn Rider, and get caught up in one of history's most notorious blood feud's in Fred Olen Ray's Bad Blood: The Hatfiends and McCoys.

Trivia: A boyishly handsome boxer-turned-actor who turned in his gloves for real after making his screen debut as a pugilist in the 1992 drama Gladiator, New York-born film and television star Jon Seda rose through the ranks in the '90s to make a name for himself as a bit player in such high-profile films as Carlito's Way and Twelve Monkeys -- though it wasn't until his 1997 debut on television's Homicide: Life on the Streets that audiences truly sat up and took notice. Those who had been following Seda's career since his early days had little doubt that the rising young star had what it took to make it as an actor, and following an Independent Spirit Award-winning role as a flawed but well-meaning husband and father in the 1994 drama I Like It Like That, major offers quickly began pouring in. An impressive run in the mid-'90s found Seda turning up in everything from such high-profile Hollywood fare as Primal Fear to such little-seen efforts as New York Cop and Michael Cimino's The Sunchaser -- the latter of which offered Seda in a particularly memorable role as a terminally-ill juvenile delinquent who kidnaps his doctor in hopes of finding a mythical healing lake. Following an impressive turn in the hit HBO prison series Oz, Seda hit his stride on the small screen with a turn as Detective Paul Falsone on Homicide: Life on the Street. By this time Seda was becoming a familiar face to audiences, and in 2000, he once again laced up his boxing gloves for a role opposite Jimmy Smits in the well-received feature Price of Glory. Despite his prominence and success in film and television, it still seemed as if Seda was awaiting the breakout role that would truly make him a household name. In 2002 he proved that he could carry a film when he took the lead in the street-gang drama King Rikki, with a role on the 2004 UPN series Kevin Hill, marking what fans hoped would be a successful return to the small screen.

Trivia: At 14, ran away from home and took a Greyhound bus to Los Angeles to pursue a career as an actor, but his parents tracked him down and sent him to a boarding school in Ireland. After graduating from high school in Omaha, he studied French, art history and theatre in Paris. Was cast as an understudy in the Broadway production of Biloxi Blues. As a 46-year-old training for the lead role in the FX series Lights Out, McCallany fulfilled a lifelong dream to fight in an amateur boxing competition, winning a three-round decision against a German heavyweight.

Trivia: Grew up in Huntington Beach, Cal. An avid surfer since the age of 8, when his sister bought him his first surfboard. Acted in commercials to pay college tuition. Turned down the opportunity to study screenwriting at New York University.

Trivia: With his lean but bold and visually powerful approach, filmmaker Walter Hill's career proved that action films can be smart, stylish, and distinctive, and his movies put a fresh spin on the traditional themes of Westerns, crime dramas, and even buddy filmsThe son of a riveter who worked in shipbuilding, Hill was born in Long Beach, CA, on January 10, 1942. He briefly followed in his father's blue-collar footsteps, earning his living in oil drilling and construction, before focusing his career on the arts. Hill studied drawing for a spell in Mexico, and later enrolled at Michigan State University, where he received a degree in Journalism. In time, he developed a passion for filmmaking and moved back to California, where he earned his first movie credits as an assistant director on such pictures as The Thomas Crown Affair and Take the Money and Run. Hill next worked as a screenwriter; two films were based on his scripts in 1972: the dark crime drama Hickey and Boggs and Sam Peckinpah's adaptation of Jim Thompson's novel The Getaway. Hill's taut, muscular screenplays, sometimes written in blank verse, earned him a potent reputation in the industry, and, in 1975, he landed his first assignment as a director when he brought his own script, Hard Times, to the screen with Charles Bronson and James Coburn in the leads. While his next project as a writer/director, The Driver, earned a cult following, Hill's third feature really put him on the map. The Warriors earned both rave reviews and controversy; the tale of a New York street gang making its way home through unfriendly territory was accused of inspiring a number of violent incidents at theaters showing the film. However, it also earned a handsome profit, allowing Hill to take on two more ambitious projects: The Long Riders, a period Western in which a number of criminal siblings join forces, and Southern Comfort, an atmospheric suspense film about men on Army Reserve exercises who discover they're fighting a real war. The director then scored a blockbuster with the Eddie Murphy/Nick Nolte comedy 48 Hours. His subsequent movies tended to be more cult-oriented than bona fide hits, but Hill's sharp visual style and tough, street-smart scripts kept him in demand, and he earned some of his strongest reviews in years for his 2002 boxing-behind-bars drama Undisputed. In 1979, Hill moved into producing, working behind the scenes on the sci-fi smash Alien, and helped produce most of his own films, as well as the successful HBO series Tales From the Crypt. He also helped end the career of the infamous and imaginary director Alan Smithee; Hill was hired to step in as director on the troubled sci-fi epic Supernova shortly before shooting began, but opted out of the project before editing was completed, and requested that his name be removed from the film. Since the Director's Guild of America's registered pseudonym for dissatisfied filmmakers, Alan Smithee, had become common knowledge in the wake of the comedy An Alan Smithee Film: Burn, Hollywood, Burn, a new assumed name was created to accommodate Hill -- Thomas Lee -- and the name Smithee was officially retired.
