Trivia: Born in 1976, Grenier grew up in Brooklyn and attended Bard College. It was during his studies that he was cast as the titular lead in the independent film The Adventures of Sebastian Cole (1998). His natural, unaffected portrayal of a young man growing up with his pre-op transsexual stepfather in 1980s upstate New York was a hit among critics, and Grenier was soon being touted as one to watch. That same year, the young actor -- who had made his film debut in the 1997 independent film Arresting Gena -- also gained a significant amount of exposure playing a member of Leonardo DiCaprio's entourage in Woody Allen's Celebrity. Following the critical and arthouse success of Sebastian Cole, Grenier was cast in his first mainstream film, Drive Me Crazy (1999). After a decidedly Manson-esque turn as a cinematic terrorist in director John Waters' Cecil B. Demented, Grenier could be seen in a small but notably less-psychotic role in Steven Spielberg's 2001 sci-fi drama A.I. He would appear in other films, like Hart's War and Anything Else, but it was the move to the small screen in 2004 with the lead on HBO's critically acclaimed Entourage that landed Grenier his most substantial notice and success to date. The massively popular show would run until 2011, and Grenier would also appear in the popular comedy The Devil Wears Prada. Grenier's interest would shift to documentary filmmaking, however, as the 2000's unfolded, and he would produce several projects, like Teenage Paparazzo and My Name is Faith, as well as the documentary series Alter Eco.

Trivia: Long Island, New York native Kevin Connolly broke into feature films and blockbuster television series roles by way of commercials; the fresh-faced star later recalled that he hawked every brand from Chips Ahoy! to Parker Brothers in front of the cameras during his early years. Cresting on this exposure, Connolly moved into bit roles in features during adolescence and gradually ascended to supporting billing. Projects in which he appeared included Rocky V (1990), The Beverly Hillbillies (1993), Angus (1995), and John Q. (2002). Connolly received elevated attention courtesy of his well-received supporting turns as Slim in the Denzel Washington-directed psychological drama Antwone Fisher (2002) and Fin in the nostalgic romance The Notebook (2004), but achieved widespread acclaim with his portrayal of Eric Murphy, one of several young men enjoying the perks of Hollywood stardom, in the HBO comedy series Entourage from 2004 to 2011. After the show ended its run, Connolly reentered the world of film, appearing in a number of projects, like the Ken Kwapis-directed romantic comedy He's Just Not That Into You, and the horse-racing drama Secretariat.Connolly made his feature directorial debut in 2997 with the black comedy The Gardener of Eden, executive produced by Leonardo DiCaprio.

Often cast in lightweight roles (Heaven Help Us [1985], The Blob [1988]), Dillon has distinguished himself in the films of director Oliver Stone with a brace of powerful characterizations: the baby-faced but homicidal teenage soldier Bunny in Platoon (1986), and real-life rock musician John Densmore in The Doors (1991). He would continue to take on a variety of projects over the coming decades, most notably titles like Criminal Hearts, and Poseidon.

Trivia: Classically trained character actor Jeremy Piven shot to stardom as Ellen DeGeneres' unforgettable, sharp-witted cousin Spence on the ABC sitcom Ellen. Born in New York City on July 26, 1965, Piven is the son of actors Byrne and Joyce Piven. He grew up in Evanston, IL, where his parents founded the Piven Theater Workshop. He studied theater at his parents' school alongside Lili Taylor, Rosanna Arquette, and pal John Cusack. The longtime friends, who began by performing Chekhov at age eight, have collaborated on several films -- including One Crazy Summer (1986), Say Anything (1989), The Grifters (1990), Floundering (1994), Grosse Pointe Blank (1997), and Serendipity (2001). They also co-founded the New Criminals Theater Company in 1989, which is now New Crime Productions, the company behind Grosse Pointe Blank and the Cusack vehicle High Fidelity (2002).A former member of the Second City National Touring Company, Piven made his small-screen debut on Carol Burnett's short-lived variety show Carol and Company in 1990. He went on to play a writer on HBO's The Larry Sanders Show and to appear on Seinfeld before starring as an unemployed father on the short-lived series Pride & Joy. Disney, who produced Pride & Joy, then created a role for him on Ellen. After the sitcom's cancellation in April 1998, Piven landed his own show, the offbeat ABC comedy-drama Cupid. Also starring Piven's real-life neighbor Paula Marshall, Cupid followed the infamous matchmaker after he had been thrown out of heaven for bad behavior and attempted to earn his reentry by uniting 100 couples in true love without using his otherworldly powers. The series won critical acclaim and earned Piven quite a following. Yet, as with many of the network's more innovative shows, ABC mishandled Cupid, shuffling it in and out of prime time until its inevitable cancellation. Undaunted, Piven returned to television a year later to guest star on Will & Grace.While Piven's film career has suffered the same ups and downs as his time on television, it is marked by numerous scene-stealing supporting performances. After making his feature-film debut in Lucas (1986), the actor appeared in Robert Altman's The Player (1992), Cameron Crowe's Singles (1992), and Tim Robbins' Bob Roberts (1992). He fell into a slump with failures like Judgment Night (1993) and Car 54, Where are You? (1994), but became a cult favorite for his portrayal of a campus misfit in P.C.U. (1994). Standout roles opposite Sarah Jessica Parker in Miami Rhapsody (1995), Robert De Niro in Heat (1995), Bill Murray in Larger Than Life (1996), and Morgan Freeman in Kiss the Girls (1997) quickly followed. He then proved to be the only good thing in Peter Berg's Very Bad Things (1998), before playing Nicolas Cage's best friend in The Family Man (2000). Piven took a respectable dramatic turn as a doomed helicopter pilot in Ridley Scott's award-winning Black Hawk Down, but returned to comedy for Old School (2003), a film by the makers of Road Trip (2000).Piven continued his work in entourage and took a starring role in Chappelle's Show director Neal Brennan's farcical comedy The Goods: Live Hard, Sell Hard in 2009. 2011 found the actor playing the dreaded Timekeeper in Spy Kids: All the Time in the World, he would portray another villain, this time in a voice role, for the children's adventure The Pirates! Band of Misfits in 2012.Then, in 2005, Piven scored the iconic role of Ari Gold on the HBO series Entourage. The show turned out to be a massive success, and Piven's profile was raised considerably, making him more of a household name, and helping him to score more interesting roles outside the show, like washed-out magician Buddy Isreal in the 2006 over-the-top action blow-out Smokin' Aces, and Damon Schmidt in the 2007 political thriller The Kingdom. In 2008, he joined the cast of the Guy Ritchie London crime movie RocknRolla.

Trivia: A former music-video girl who appeared in clips by Pharrell and Ludacris before making her big-screen debut in ATL, Los Angeles native Lauren London possesses a small-town beauty with a distinctive smile and a slight city-girl edge. It was during London's stint in the Las Angeles public school system that the aspiring actress first began dabbling in theater and drama, and though she would later be home-schooled for her last three years of high school, the desire to perform never went away. Appearances in a handful of music videos helped to get London comfortable in front of the cameras, and when buzz began to build around the production of an upcoming film called ATL, she hired an acting coach and convinced director Chris Robinson's assistant to get her an audition. Despite being two hours late for the audition, London performed well enough under pressure to land the role of roller-skating rich girl New New -- who changes her identity and soon begins dating former high-school hotshot Rashad (played by hip-hop recording artist T.I.). With buzz around the rising starlet subsequently beginning to gain momentum, London next appeared in episodes of Everybody Hates Chris and Entourage while preparing for a role in the holiday-themed family drama This Christmas. She had a small part in Next Day Air, and landed a major role in the comedy I Love You, Beth Cooper. Two years later Tyler Perry tapped her to appear in Tyler Perry's Madea's Big Happy Family.

Trivia: Stories abound about the length to which American character player/writer Jonathan Sadowski ventured to pay his dues as an aspiring Hollywood talent and gain that elusive "in" to the club of the elite. Some of the anecdotes are confirmed, and some are not, but the fact that Sadowski traveled that well-worn road of many an actor by waiting tables is undeniable. The then-hopeful took a job at the Sunset Boulevard diner called The Griddle Café; he and fellow server/screenwriting partner Ben Branstrader subsequently authored a script called "This Man Smith," and pitched it, tableside, to producer J.C. Spink (of The Ring and Monster-in-Law fame) when the mogul came in for a bite in 2005. Spink reportedly signed the young men on the spot.Sadowski cut his acting chops far more quickly than he received onscreen writing credit, however, and the performer (who had already enjoyed a favorable run on American Dreams prior to his impromptu meeting with Spink) continued to make appearances in Hollywood A-list features over the next several years. These included Paul in She's the Man (2006), director Andy Fickman's teen comic update of Shakespeare's Twelfth Night and Trey in the Bruce Willis actioner Live Free or Die Hard (2007). Sadowski also signed for a role in the Ryan Shiraki-directed farce Spring Breakdown (2008), about a trio of thirtysomething girls who decide to crash a spring break resort popular with college coeds.

Trivia: The only child to Jewish parents in Miami, FL, Brett Ratner was accepted to N.Y.U. at the age of 16. Attending the Tisch School for the Arts, he received funding from Steven Spielberg's Amblin Entertainment for his senior project Whatever Happened to Mason Reese?, a documentary about a child star. After forming a friendship with Def Jam producer Russell Simmons, Ratner began directing music videos for stars such as Jay-Z, Mariah Carey, and Madonna. It was Simmons who helped him get his first big break, directing Money Talks with Chris Tucker and Charlie Sheen. Ratner worked with Tucker again for his sophomore effort, Rush Hour, a Jackie Chan comedy that broke box-office records for New Line Cinema. A brief departure into romantic comedy with The Family Man was not very well received, but the wild success of Rush Hour 2 brought him back into the limelight, and he soon landed the director's chair for The Silence of the Lambs prequel Red Dragon. He helmed the pilot of the FOX drama Prison Break, and was behind the camera for the superhero sequel X-Men: The Last Stand before returning to familiar territory in 2007 with Rush Hour 3. He created one of the segments for the omnibus film New York, I Love You, and directed Eddie Murphy and Ben Stiller in the ensemble action comedy Tower Heist in 2011. He was tapped to direct the 2012 Oscar telecast, but was fired from the job, allegedly after making a series of insensitive statements.

Trivia: Known for her feline eyes and brash New York attitude, Queens native Debi Mazar began her show business career behind the scenes as a makeup artist for a star-studded clientele, the most lucrative of the bunch being Madonna. Attracted by her unique features, the iconic pop singer cast Mazar in the music videos for "True Blue," "Deeper and Deeper," and "Papa Don't Preach." It wasn't until 1990, however, that Mazar made her film debut as the cokehead girlfriend of Henry Hill (Ray Liotta) in Martin Scorsese's GoodFellas. After portraying a series of small but indelible characters in Oliver Stone's The Doors, Spike Lee's Jungle Fever, and Jodie Foster's Little Man Tate (all 1991), Mazar had developed a small but devoted following and a reputation solid enough to land her the tough-talking role of legal defense secretary Denise Iannello on ABC's legal drama Civil Wars (1991-1993), a role she would reprise for NBC's L.A. Law in 1994.After taking on several more tiny supporting parts throughout the early '90s, including one which would reunite her with Jungle Fever director Spike Lee (in the Oscar-winning Malcolm X [1992]), Mazar made her debut as a lead character in Money for Nothing (1993), a blue-collar crime comedy co-starring John Cusack, with whom she would work for a second time in Woody Allen's Bullets Over Broadway (1994). After a brief performance as a manicurist in television's Witch Hunt (1994), Mazar could be found in the role of a femme fatale alongside Drew Barrymore, Jim Carrey, and Val Kilmer in Batman Forever (1995), and would portray an idealistic HIV-positive thief in Red Ribbon Blues (1995). Red Ribbon Blues wasn't the last time Mazar would delve into the complex world of sex and gender-related prejudice -- in 1996's Girl 6, Mazar co-starred as an anonymous member of a phone sex business, while Things I Never Told You found her playing a transsexual. Shortly afterward, Mazar chewed a respectable amount of scenery as one of Long Island barfly Tommy's (Steve Buscemi) potential hook-ups in 1996's Trees Lounge. The actress continued to exhibit her versatility in a series of roles during 1997, including those of a sleazy television show producer in Meet Wally Sparks, an intergalactic waitress in Space Truckers, and two decidedly more serious performances in the gay & lesbian drama Nowhere and Nick Cassavetes' romantic drama She's So Lovely.With the notable exceptions of bleaching her trademark jet-black tresses for 1998's Frogs for Snakes with Robbie Coltrane, and her role as Debbie De Luca in Michael Mann's tobacco industry exposé The Insider (1999), Mazar spent much of the late '90s on the small screen. After the failure of CBS's sitcom Temporarily Yours (1997), Mazar played lead roles in David and Lisa (a psychological drama co-produced by Oprah Winfrey) and NBC's Witness to the Mob. Following another NBC sitcom appearance in the short-lived Working (1998), the actress starred in 2000's CBS drama That's Life as an advice-dispensing hairdresser. In 2002, Mazar played right-hand woman to multi-millionaire Clark Devlin (Jason Isaacs) in Jackie Chan's The Tuxedo, and went on to offer a poignant monologue in Ten Tiny Love Stories the same year. In 2004, Mazar took on a supporting role in the crime comedy Be Cool with John Travolta and Uma Thurman, and starred in Dennis Brooks' independent film Goodnight, Joseph Parker.She had a major role in 2008's A Beautiful Life, and that same year had a small part in the ensemble of The Women. In 2012 she could be seen in the porn queen biopic Lovelace.
