Trivia: Notorious for spearheading the "teen pop revolution" of the mid to late '90s, alongside Britney Spears, Christina Aguilera, and others (and the inheritor of superstardom from male heartthrobs of earlier generations such as David Cassidy and Donny Osmond), Justin Timberlake attained a reputation as one of the pop music scene's most talked about celebs. He also became a source of constant tabloid fodder -- not only for his relationships with Spears, Cameron Diaz, and others, but for his allegedly unbridled private life.Timberlake launched his career as a youngster on the Mickey Mouse Club set, then made his name as a member of *NSYNC and as a soloist before branching out into films in the very early 2000s. As an actor, he began small, with a cameo appearance in the Ben Stiller-directed Zoolander -- an off-the-wall farce about a bunch of inane male models led by Stiller and Owen Wilson. While Timberlake's walk-on was a bit part at most, the exposure helped him expand his range and his repertoire, while the subject of the film coyly spoofed his public image. Small-screen appearances on The Osbournes and Saturday Night Live followed, but it wasn't until 2005 that the then 24-year-old Timberlake became a top-billed movie star. In that year's Edison Force, in which Timberlake co-starred with movie giants Kevin Spacey and Morgan Freeman, the former teen idol played Joshua Pollack, a straight-faced, straight-arrow journalist determined to take on a league of crooked rollers. The picture was released straight to DVD in late 2006 and earned tepid reviews.The singer upped his film appearances in 2006, with a plethora of first-run roles. He stuck to the crime thriller genre with his follow-up to Edison, Alpha Dog (2006). Directed by Nick Cassavetes (She's So Lovely, John Q.) from his own script, the picture stars Emile Hirsch (The Girl Next Door) as an über-powerful drug dealer who kidnaps a youngster to collect a ransom the boy's older brother's tab; Timberlake plays one of Hirsch's henchmen, who inducts the tyke into the wild side of life. In 2007's Black Snake Moan, Timberlake plays the boyfriend of Christina Ricci's nympho Rae -- a girl who becomes the hostage of an aging African-American blues musician (Samuel L. Jackson). Timberlake also appears in a supporting role in Southland Tales (2006, directed by Donnie Darko's Richard Kelly) and voices the rebellious prince Artie (a young King Arthur) alongside longtime paramour Diaz in 2007's Shrek the Third. In 2008 he played potent hockey player Jacque "Le Coq" Grande in Mike Myers comedy The Love Guru, but he scored the most high-profile success of his film career in 2010 when he played Napster founder Sean Parker in David Fincher's award-winning Facebook film The Social Network. He followed that up in 2011 with the romantic comedy Friends With Benefits and the sci-fi film In Time. The next year he appeared in the Coen brothers' Inside Llewyn Davis.

Trivia: Wide-eyed actress Amanda Seyfried is best known to audiences for her hilarious performance as slow-witted but popular Karen Smith in the 2004 film Mean Girls. The former child model had graduated from high school the year before, though throughout her secondary education Seyfried had been acting on the popular soaps As the World Turns and All My Children, and by the time Mean Girls producers cast her for her big break, she was an experienced performer. She followed up the film's success with a role on the popular series Veronica Mars, playing the title character's murdered best friend in a series of "Laura Palmer-esque" flashbacks. She also took a role on the popular and controversial series Big Love before signing on to star in the big-screen adaptation of the popular Broadway play Mamma Mia!, a musical about a bride-to-be searching for her real father, set to the tunes of the popular Swedish disco group ABBA. She stretched her range with the 2009 erotic drama Chloe, and starred opposite Channing Tatum in the Nicholas Sparks adaptation Dear John the next year. In 2011 she was the lead in Red Riding Hood, and played opposite Justin Timberlake in the sci-fi film In Time.

Trivia: A soft-spoken, fair-skinned actor with startling blue eyes, a penchant for playing volatile characters, and a reluctance to forsake his critically lauded stage career for a life in film, American audiences may best know Irish actor Cillian Murphy as the bike courier making his way through infected London in director Danny Boyle's apocalyptic thriller 28 Days Later. Though the film may have been Murphy's first to find wide stateside exposure, he has been appearing onscreen in the U.K. and his native Ireland since 1997. Born in Douglas, Cork, Ireland, in 1974, Murphy's father was a school inspector and his mother a French teacher. Attending school at Presentation Brothers College Cork while intending to enter into a career in law, Murphy was an avid rugby player who was turned on to the Concordia Theater's unique stage productions in his fourth year. Murphy soon signed up for a workshop with Concordia's Pat Tiernan and it quickly became apparent that he had a natural flair for the stage. Soon cast as the wildly emotional Pig in Concordia's production of Disco Pigs, Murphy debuted to rave reviews and was soon skipping school to go on tour with the production. Though his acting had initially begun as a hobby and a way to kill time on the weekends, it was quickly taking over his life and a career in law seemed less and less appealing. Though he would attempt to continue his law studies, it was soon obvious to Murphy that his heart just wasn't in it.Subsequently cast in a series of interesting and complex roles, Murphy made his feature debut in the 1998 film Sweety Barrett and quickly followed with the coming-of-age comedy drama Sunburn. Though it was obvious that his stage talents translated well to the silver screen, Murphy still maintained that the rush of theater couldn't be touched by celluloid. The problem in Ireland of suicide and poor mental health among young men prompted Murphy to accept a role in the 2000 drama On the Edge, and his role of a suicidal psychiatric patient proved memorable and affecting. Following How Harry Became a Tree (2001), it was time to adapt Disco Pigs into a feature film, and with director Kirsten Sheridan at the helm, Murphy reprised his role of Pig to enthusiastic results. By the time 28 Days Later rolled around, it seemed that everyone except United States audiences were familiar with the rising star, and with the stateside release of the film in mid 2003, all that was soon to change. Noting that, in his opinion, the best actors alternate frequently between stage and screen, Murphy strived to keep a balance as his growing popularity found his film career taking precedence. Following 2003's Zonad, Murphy began preparation for such features as Intermission and Girl With a Pearl Earring (both 2003).Murphy's resumé amassed higher and higher profile roles. 2005 brought his most popular film to date as he played the villain opposite hero Christian Bale in Batman Begins. Murphy's "boy next door" face seemed to make his performance as the menacing Scarecrow all the more disturbing, and he would go on to play the bad guy again later that same year in Red Eye, though this time he wore makeup to cover his boyish features. Soon he was donning even more makeup, however, as a transsexual in the indie hit Breakfast on Pluto. Playing both a victim and a hero in the U.K. of the 1970s, Murphy's ethereal performance as a boy who leaves his Ireland home to live as a woman in London was praised by critics, and the film was a cult success. He followed it up with another passion project in 2006: Ken Loach's award-winning The Wind That Shakes the Barley, a look at the Irish Republicans of the early 20th century and the anti-British rebellion that would continue to tear families apart for decades to come. He next signed on to star with Lucy Liu in the romantic comedy Watching the Detectives, another independent venture that would find Murphy playing a shy film geek who's pulled out of his movie collection and into the real world when he meets a real-life femme fetal, played by Liu. Also on Murphy's calendar for 2007 was the Danny Boyle psychological sci-fi thriller Sunshine, about a small crew of astronauts sent to reignite Earth's dying sun. Over the next few years, Murphy would apper in a number of other films, like Inception, Retreat, and Broken.

Trivia: A native of Minneapolis, MN, Vincent Kartheiser made a name for himself in the late '90s by choosing unlikely fare for an actor who, at the time, had just earned the right to drink legally. Making his screen debut in a bit role in the 1993 tearjerker Untamed Heart, opposite Marisa Tomei and Christian Slater, the blue-eyed, brown-haired Kartheiser subsequently found himself being cast in family fare, most memorably the action-adventure drama Alaska, in which he starred opposite Thora Birch and Charlton Heston (whose son directed the film). The film led to the leading role in the kiddie tech thriller Masterminds, which featured the young actor as a whiz kid who takes on an evil private-school headmaster, played by Patrick Stewart. Kartheiser's next role, however, would be his most defining in terms of establishing his range and presence. Tapped to play Bobby, a drug-addled, homeless street urchin in Larry Clark's Another Day in Paradise, a gritty look at the lives of a pseudo-family immersed in crime, Kartheiser rose to the challenge with a fearless, powerful performance, acting with such established pros as James Woods and Melanie Griffith. The film earned many accolades for the young actor, who then appeared in Strike! (later retitled All I Wanna Do), a barely released comedy set in a 1960s female boarding school. The film featured contemporaries Kirsten Dunst, Gaby Hoffmann, and Monica Keena, the last of whom was co-star of Kartheiser's next project, Crime & Punishment in Suburbia. Screened at the 2000 Sundance Film Festival, Crime & Punishment in Suburbia was a moody, updated take on Dostoyevsky's Crime and Punishment, set in a modern high school. Kartheiser played Vincent, a reticent teenager obsessed with a girl (Keena) who is slowly going over the edge. The film furthered his reputation as a daring performer uninterested in taking the safe route, a path many actors of Kartheiser's generation followed for higher visibility. After a few little-seen films, Kartheiser next turned up on the supernatural comedy drama series Angel in 2002. In a truly original role, he played Connor, the miraculous human son of vampires Darla (Julie Benz) and the titular Angel (David Boreanaz). Thanks to being reared in an alternate hell dimention, Connor had more than a few chips on his shoulder upon his return to L.A.; his adolescent angst and rebellion was one of the main focuses of the series' fourth season. Returning to film work, Kartheiser went on to star in the well-received coming-of-age drama Dandelion, which was shown at the 2004 Sundance Film Festival.He was part of the cast of the crime drama Alpha Dogs in 2006. But, he landed his breakthrough part in 2007 when he was cast as Pete Campbell, a junior ad executive, on AMC's award-winning drama Mad Men. In 2011 he played the bad guy in the sci-fi thriller In Time and provided the voices for a pair of the characters in the Oscar winning animated feature Rango.

Trivia: On many an occasion, Olivia Wilde's sleek hair (which alternated between blonde and coal black), sultry figure, and haunting blue eyes typecast her in the mold of an evil seductress and vamp. The N.Y.-born Wilde -- not a blood relation to the famous writer Oscar Wilde, as is commonly assumed, but one inspired by him, who borrowed his surname -- launched into show business with a portrayal of Jewel Goldman, the female lead of Jerry Bruckheimer's short-lived Fox drama Skin (2003). The series constituted an update of Romeo and Juliet and depicted the romance between a porn producer's daughter and a district attorney's son. It folded not long after it premiered, but provided a convenient showcase for Wilde's talents. After key roles in two drug-themed features -- the Nick Cassavetes-directed Alpha Dog and director John Herzfeld's Bobby Z -- Wilde catapulted sensationalism-hungry viewers to their television sets when she portrayed a lesbian bartender who attempts to seduce lovely Mischa Barton on The O.C. She then received regular billing as Jenny Reilly on The Black Donnellys (2007), an NBC series about the exploits of an Irish crime family residing in Hell's Kitchen, which didn't make it past its first season. Wilde rebounded quickly with a coveted role on the smash-hit Fox medical series House, joining the cast during the show's fourth season. She remained on the show for three seasons, and also built up a big-screen career with roles in Year One, Tron: Legacy, The Change-Up, Butter, Cowboys & Aliens, and People Like Us. Once leaving House, she largely focused on her film work, often alternating bigger budget films (like 2013's Rush) with smaller, independent films (like 2013's Drinking Buddies, which she also executive produced).

Was tipped to star in Superman Returns (2006), until a change of directors led to Brandon Routh being cast as the titular superhero. Gained a higher profile with starring roles on the short-lived ABC drama Traveler and the acclaimed USA Network series White Collar. Named People magazine's Sexiest Rising Star in 2009. Was awarded a Golden Globe in 2015 for Best Performance by an Actor in a Supporting Role in The Normal Heart.

Trivia: Born on a Belgian army base, curly brown-haired Johnny Galecki grew up in Chicago and started acting professionally at the age of 12. He made his feature film debut in 1988 as River Phoenix's little brother in A Night in the Life of Jimmy Reardon. He then assumed the role of Rusty Griswold in National Lampoon's Christmas Vacation, and gained his first regular role on a TV series as Robert Ulrich's son in American Dreamer. In 1991, he starred in the made-for-TV movie Backfield in Motion, co-starring the production team of Roseanne and Tom Arnold. The next year, Galecki joined the cast of Roseanne as Darlene's sensitive and put-upon boyfriend David Healy. He stayed on the show until its final season in 1997, although he wasn't on very much during its last few years. His other television credits include several guest appearances, leading roles in made-for-TV movies, and a part on the short-lived Head of the Class spin-off Billy. After Roseanne ended, he got back into features with small parts in I Know What You Did Last Summer, Bean, and Suicide Kings. He continued playing slightly effeminate sensitive males in The Opposite of Sex and Morgan's Ferry. After bit parts in Bounce, Playing Mona Lisa, and Vanilla Sky, Galecki played a leading role in the comedy thriller Bookies, which premiered at the 2003 Sundance Film Festival. In 2007 he landed the leading role in the sitcom The Big Bang Theory and it grew to be one of the most popular shows on TV, earning Galecki Emmy, Golden Globe, and Sag nominations in 2011 for his work on the show. He maintained his movie career in projects such as Hancock and In Time.

Trivia: A veteran of television, Collins Pennie began his career with a stint on As the World Turns and also guest-starred on shows like CSI: Miami and Without a Trace.

Trivia: Actor Toby Hemingway took his Hollywood bow in the mid- to late 2000s with a pair of supporting roles in two extremely different films that displayed his versatility: Renny Harlin's supernatural horror opus The Covenant and Robert Benton's romantic ensemble drama Feast of Love (2007).

Trivia: A photogenic young actor whose successful modeling career no-doubt helped to set him at ease in front of the camera before he was bitten by the acting bug, handsome Alex Pettyfer had essayed only one role on the screen before being launched into what has been referred to by some as the most physically demanding performance for a young actor ever attempted -- the role of teenage super-spy Alex Rider in the high-flying 2006 adventure Stormbreaker. Pegged by industry insiders as the next Brad Pitt thanks to a winning combination of good looks and promising talent, the rising star appeared in widely seen advertising campaigns for such well-known companies as The Gap before following actor father Richard Pettyfer to the silver screen. Educated as a border student at Shiplake College in Oxfordshire, England, Alex commuted between his school and his Windsor home while completing his secondary education. The procurement of an L.A. agent quickly resulted in the casting of Pettyfer in a British ITV production of Tom Brown's Schooldays, a fateful turn which found the burgeoning actor developing much the same relationship with co-star Stephen Fry off screen as his character shared with Fry's friendly but bemused headmaster onscreen. Subsequently beating out over 500 hopefuls to land the role of adolescent secret agent Alex Rider in Stormbreaker, the big-budget screen adaptation of author Anthony Horowitz's popular series of teenage adventure novels, Pettyfer began the grueling training process to get in shape for the role of a lifetime. He went on to appear in the Beauty and the Beast redo Beastly, the sci-fi film In Time, and the action film I Am Number Four. In 2012 he appeared in the Steven Soderberg male stripper film Magic Mike.

Trivia: Connecticut native Jesse Lee Soffer began his career at the tender age of eight when he appeared in the film Matinee, about the sci-fi movies that were popular in the 1950s.

Trivia: A stunning model whose smoldering layouts in such high-fashion magazines as Elle, Glamour, and Vogue found her gracing catwalks across Europe, Rachel Roberts' seeming lack of physical imperfection caught the attention of producers preparing a film about the first virtual-actress and placed her as the ideal candidate for the role of the ultimate special effect in Simone (2002). Born in British Columbia, Canada, Roberts began her career at age 16. Going international shortly thereafter, the ethereal beauty was courted by numerous fashion magazines and eventually appeared in ads for Victoria's Secret and Banana Republic in addition to gracing the pages of the 2000 Sports Illustrated Swimsuit Issue. Though her film debut remained shrouded in mystery due to a gag order issued by New Line Cinema, in addition to Roberts' working under the pseudonym Anna Green (short for Anamorphic Green-Screen, a special effects device which offers the ability to implement digital effects in film) during production, the film's debut found the true identity of the model-turned-actress ultimately revealed. Nevertheless, producers noted that certain aspects of the character, such as vocal patterns, were an amalgam of traits from other Hollywood actresses.
