Trivia: Canadian-born actor Seth Rogen tapped into his skills as a comedian when he was only 13, signing up for comedy classes and honing his deadpan style. He tooled around as an amateur for a few years but eventually took his act down south, hoping to find success as an actor and standup comedian in the U.S. He was soon discovered by Judd Apatow and was cast in his short-lived series Freaks and Geeks. After its cancellation, Apatow cast Rogen in his next series, Undeclared -- for which Rogen significantly contributed as a writer. Undeclared met the same fate as Freaks and Geeks and was canceled mid-season, but both series became surprisingly hot cult hits upon their DVD releases. Rogen went on to write for Da Ali G Show and take minor roles in Donnie Darko and Anchorman: The Legend of Ron Burgundy before being tapped by Apatow once again for a new project, this time on the big screen. The film was 2005's The 40-Year-Old Virgin, and Rogen's role as Steve Carell's well-meaning friend Cal finally brought him the large-scale success that made his comic skills a valuable commodity. Rogen also acted as co-producer on the film, which was touted as the funniest movie in years by critics and audiences alike, eventually grossing well over a hundred million dollars. There was obviously good chemistry on the set of The 40 Year Old Virgin, so Rogen signed on to appear in Apatow's 2007 comedy Knocked Up. Appearing alongside his old cast mates Paul Rudd and Leslie Mann, Rogen starred as a man who is forced to deal with serious unforeseen consequences when his one-night stand becomes pregnant. After the filmmakers' initial plans to cast Anne Hathaway in the opposite role fell through, Grey's Anatomy star Katherine Heigl signed on to star as the female lead. The smash success of Superbad made him one of the biggest comedy stars of his generation and led to Pineapple Express, a pot comedy opposite James Franco. He was Zack in Zack and MIri Make a Porno, and took a screenwriting credit on Drillbit Taylor in 2008. He lent his distinctive gravelly voice to a number of animated films including Kung Fu Panda and Monsters vs. Aliens. In 2009 he stretched himself, reteaming with Apatow for Funny People, and taking the lead in the black comedy Observe and Report. In 2011 he was The Green Hornet, but he also appeared as the best friend to a young cancer victim in the comedy 50/50. He also played the husband of Michelle Williams in Sarah Polley's Take This Waltz.

Trivia: Though Australian-born actress Rose Byrne made her film debut in 1994, when she played a supporting role in the eccentric drama Dallas Doll alongside Sandra Bernhard and Jake Blundell, her breakout performances within her native country were both on the small screen; namely, in the soap opera Echo Point and the long-running drama series Heartbreak High. After developing a fan base and gaining some critical recognition, Byrne was cast alongside fellow Aussie Heath Ledger in Two Hands (1999), which featured the actress playing an innocent country girl whose would-be suitor has unwittingly found himself in the midst of a mafia scandal. Though she undoubtedly caught the eye of American filmmakers after Two Hands' premiere at the 1999 Sundance Film Festival, Byrne wouldn't appear in an American film until several years later, when she made a very small appearance in a very big movie -- Star Wars: Episode II -- Attack of the Clones. However, before Star Wars, Byrne starred in two little-known, but nonetheless significant, Australian parts, including her first lead role in The Goddess of 1967 (2000), in which she portrayed a blind, emotionally unstable orphan, and My Mother Frank, which featured her as the unrequited love interest of a pining college student. After the 2002 release of Attack of the Clones, Byrne could be seen in a minor but indelible supporting role in Matt Dillon's City of Ghosts. Byrne went on to perform in two critically acclaimed Australian features -- The Rage in Placid Lake (2003) and The Night We Called It a Day (2003) -- as well as the U.K. release I Capture the Castle (2003), in which she co-starred as the beautiful daughter of a once-grand English family. In 2004, Byrne played a supporting role in Wolfgang Petersen's big-budget historical epic Troy, and went on to star with Josh Hartnett, Matthew Lillard, and Troy alumna Diane Kruger in director Paul McGuigan's thriller Wicker Park. In 2006 she was cast in a supporting role in Sofia Coppola's Marie Antoinette. In 2007 she had a hit on the small-screen as one of the leads in the series Damages. Although she continued to work steadily in movies as well, she didn't find herself in a big hit until 2011 when she was one of the main characters in the Oscar nominated comedy Bridesmaids. That same year she also appeared in X-Men: First Class as Dr. Moira MacTaggert.Byrne soon became a mainstay in the comedy world, appearing in The Internship, Neighbors and Spy. She also appeared in the 2014 remake of Annie, playing Grace, and reprised her role of in X-Men: Apocalypse (2016).

Trivia: Actor Zac Efron's career began when he was just 11 years old, when his parents took note of his tremendous singing talent. They let him audition for a production of Gypsy, and he won a small role in a production that would run for 90 performances. He would eventually graduate to on-screen acting, scoring a recurring role on the hit series Summerland in 2004. This would seem like his big break, but an even bigger role would come the next year, in the hugely popular Disney feature High School Musical. Efron immediately earned a strong, loyal fan base, going on to star in big screen projects like Hairspray, 17 Again, Charlie St. Cloud, and The Lucky One.

Trivia: Made his TV debut in a 2006 episode of 7th Heaven. Was a regular on the short-lived 2008 Fox sitcom Do Not Disturb; subsequently joined the cast of Scrubs for the series' ninth season.

Trivia: American actor Christopher Mintz-Plasse took his cinematic bow in 2007 in the Greg Mottola-directed comedy Superbad. In that picture, Mintz-Plasse played a nerdy but extremely resourceful young man who procures a lousy fake ID and gains the friendship of two wild cops. He followed up with parts in Role Models and Year One, and lent his distinctive voice to family films like Marmaduke and How To Train Your Dragon. He had a major part in the remake of Fright Night in 2011.

Trivia: Lisa Kudrow first made her name playing Phoebe, the ditzy, New Age member of the titular close-knit pals on NBC's highly successful sitcom Friends. Since then, she has bridged the gap between television and film with undeniable success, winning particular acclaim for her role as an uptight school teacher in Don Roos' The Opposite of Sex (1998).Born in Encino, California on July 30, 1963, Kudrow earned a degree in biology from Vassar College before beginning her acting career. After college, she joined the Los Angeles improvisational group, The Groundlings, at the urging of family friend Jon Lovitz. Improv paved the way for more work, and Kudrow was soon appearing in bit roles in a number of films. Her first real break didn't come until 1993, when she began appearing on the TV sitcom Mad About You as Ursula, the waitress from hell. Real fame came in 1994, when the actress was cast as Phoebe on Friends; the enormous success of the show gave her both wide recognition and a steady day job. Kudrow's first leading role on the big screen was as one of the titular heroines (alongside Mira Sorvino) of the 1997 comedy Romy and Michele's High School Reunion; unfortunately, her character was little more than a film version of Phoebe. Fortunately, Kudrow got to widen her range a little further that same year with a starring role in the independent drama Clockwatchers, portraying a struggling actress alongside the likes of Toni Collette and Parker Posey. The following year, Kudrow won raves and critical respect for her turn in The Opposite of Sex, a scathing black comedy in which she gave a comic and poignant performance as an embittered woman coping with the death of her brother, the presence of her best friend's malicious little sister (Christina Ricci), and the romantic attentions of Lyle Lovett. The acclaim she received for her portrayal was complemented the same year with an Emmy Award for her work on Friends. In 1999, Kudrow shared the screen with Robert DeNiro in the comedy Analyze This, and later that year she starred with Diane Keaton and Meg Ryan as three sisters dealing with the imminent death of their irritating father (Walter Matthau) in the comedy Hanging Up, directed by Keaton and written by Nora Ephron and Delia Ephron.As the new millenium unfolded, Kudrow would prove to be a strong force on screen, appearing in a number of acclaimed films, like Wonderland, Happy Endings, The Other Woman, Easy A, and in the comedy series Web Therapy.

Trivia: Actor Jake Johnson began his career in the virgin territory of the Internet, appearing in the popular Michael Cera web series Clark and Michael in 2006. He would go on to make appearances on Curb Your Enthusiasm and The Unit, as well as in the David Mamet film Redbelt, before collaborating with Cera once again for 2009's Paper Heart. He appeared in the comedy Get Him to the Greek, and had a very busy 2011 with parts in No Strings Attached, A Very Harold & Kumar Christmas, and a major part in the new FOX sitcom New Girl.

Trivia: With her role as a memorably over-caffeinated college freshman on television's critically praised Undeclared, youthful actress Carla Gallo has endeared herself to former campus dorm-rats nationwide. And though her actual age may betray the naïve nature of those making the leap from the high school hallways to the college campus, Gallo has succeeded in making her television alter ego believable, in part by drawing on the vivid recollections of her college career. Born in Brooklyn, NY, Gallo attended the LaGuardia School of Performing Arts before setting her sights on Cornell University. Like her television counterpart, Gallo dabbled in numerous potential careers before pursuing a career as an actress, though the lure of the theater was too magnetic to resist and the formerly undeclared student graduated a few short years later with a Theater Arts degree. Being nominated for an Independent Spirit Award for her feature debut in 1994's Spanking the Monkey proved to be a good start for the fledgling thespian, and though it would be five more years until her next feature role, Gallo would next appear in The 24-Hour Woman in 1999. With small-screen appearances in both E.R. and Law & Order priming her for her work on Undeclared, the actress approached the series on a positive note after hitting it off early on with series creator Judd Apatow. As someone who encouraged improvisation, Apatow often drew on Gallo's previous college experiences to make the character more multidimensional and believable. Thinking back to the frantic all-night cram sessions of her college days, Gallo recalled a session in which her synapses fired on overdrive due to an oversaturation of caffeine. Apatow encouraged her to expand on such recollections (recollections that often found their way into the show), which were a key factor in his aspiration to create a realistic portrayal of the college experience, warts and all.
