Trivia: Studied piano from the age of 6 and originally majored in music at Oberlin College, but ultimately decided to pursue acting. Early in his career, worked as an assistant to casting directors, which provided unintentional research for his breakout role as Lloyd, assistant to agent Ari Gold on HBO's Entourage. Won Asian Excellence Awards for Supporting Television Actor in 2007 and 2008 for his work on Entourage. Has appeared in commercials for Domino's, Dr. Pepper, Chevrolet and Wendy's.

Trivia: Actress Rosanna Arquette, the granddaughter of actor Cliff Arquette (aka "Charley Weaver"), was born into a theatrical family; her father was a founding member of the Committee, an improvisational theater troupe. As a youth she moved often with her family. At age 17 she appeared on the Los Angeles stage in Metamorphosis. Her family settled in Virginia, where she worked in local theater where she was spotted by a casting director. She soon had much work in TV movies in the late '70s. She debuted onscreen in More American Graffitti (1979). Her breakthrough came with her portrayal of condemned murderer Gary Gilmore's girlfriend in the TV movie The Executioner's Song (1982), which earned her much praise. That success led to a lead role in John Sayles's Baby, It's You (1983). She gained her greatest fame in the hit film Desperately Seeking Susan (1985), co-starring Madonna. From there she has maintained a steady screen career, usually playing kooky, off-beat, spacey, slightly eccentric women. She is the sister of actress Patricia Arquette.

Trivia: With his handsome, everyman looks and strong abilities on stage and screen, actor Tate Donovan has endured to become one of the most talented actors that no one recognizes. Not that this is necessarily a bad thing; with previous girlfriends such as Sandra Bullock and Jennifer Aniston and solid performances in Clean and Sober (1988) and Memphis Belle (1990), it's readily apparent that he has the charm to match his talent. A Tenafly, NJ, native who took up acting in his teens, Donovan's early screen appearances came with troubled teen roles in such efforts as Not My Kid and Into Thin Air (both 1985), as well as a memorable appearance in the 1986 sci-fi adventure Space Camp. A move to Los Angeles found Donovan closer to the world of film production while he pursued his higher education at U.S.C., and it was there that he made the acquaintance of longtime friends such as George Clooney. A post-collegiate role in Memphis Belle (1990) proved that Donovan was indeed honing his skills in front of the camera to good effect, and following an appearance as a recovering drug addict in Clean and Sober (1988), he took his first leading role in the 1992 romantic comedy Love Potion No. 9. Though a relationship with that film's co-star, Sandra Bullock, would result in an engagement, the couple parted ways two short years later, and Donovan began a series of appearances in such art-house efforts as Ethan Frome (1993). A role in the Buena Vista comedy Holy Matrimony (1994) found Donovan getting in good with the folks at Disney, and in three short years he would be providing the voice for the eponymous character in the animated Disney adventure Hercules. More success came in the late '90s with appearances in the popular television series Ally McBeal and Friends, and in addition to a memorable appearance in Homicide: Life on the Street, Donovan gained even more exposure when he was spotted around Tinseltown with high-profile squeeze Jennifer Aniston. Though such later efforts as The Office Party (2000) and Exposed (2002) went largely unseen, Donovan returned to the small screen in 2003 with supporting roles in the series The O.C. and Mister Sterling. Over the coming years, Donovan would continue to appear in several projects, including movies like The Pacifier, Shooter, and Argo, as well as TV series like The O.C. and Damages.

Trivia: Best known as the husky-voiced, no-nonsense Lt. Sally Solomon on the hit NBC fantasy sitcom 3rd Rock from the Sun (1996-2001) -- a role she played, opposite heavyweights John Lithgow and Jane Curtin, for the entire six-year run of the series -- fair-haired Kristen Johnson parlayed her success from that effort into a handful of A-list cinematic releases, beginning in 1999. After 3rd Rock wrapped in spring 2001, Johnston's movie activity crescendoed dramatically, and she became ever-present as a character player in the supporting casts of Hollywood feature films.Born January 20, 1967, in Washington, D.C., Johnston moved with her family to Wisconsin and attended high school in suburban Milwaukee, where prescient classmates voted her "Biggest Ham" and "Most Likely to be a Celebrity." Unusually tall for her age (6 ft. at age 13), with a booming, authoritative voice and an outsized personality, Johnston stood out from the crowd and reportedly struggled with self-doubt as a result; she later termed her height "incredibly distressing." The aspiring actress learned self-acceptance early on, however, as she attended NYU and studied drama there. For almost ten years, Johnston struggled as an up-and-coming actress, holding down assorted jobs and working on Broadway and off-Broadway productions, until an NBC executive noticed her and was instrumental in enlisting her as Sally on 3rd Rock. Johnston doubled this up with a 1998 guest appearance as herself on The Larry Sanders Show, then debuted cinematically the following summer as Ivana Humpalot in Austin Powers: The Spy Who Shagged Me (1999). Johnston ascended to higher billing as Wilma Slaghoople, the wife of Fred Flintstone (a role she inherited from Elizabeth Perkins) in the family-friendly, effects-heavy Stone Age comedy The Flintstones in Viva Rock Vegas (2000).Although 3rd Rock from the Sun, as indicated, ended its original network run in mid-2001, Johnston took a couple of years off, resurfacing in 2003 with a guest appearance on the shortlived courtroom seriocomedy Queens Supreme (produced by Julia Roberts). Johnston followed this up with several additional big-screen turns over the next few years. These included a supporting role in William Tannen's all-star showbiz satire Nobody Knows Anything (2003); the part of Fran -- an envious friend of newly involved Caroleen Feeney -- in Hal Salwen's quirky indie romantic comedy Duane Incarnate; a brief supporting turn as Coach Divers in Paul Dinello's big-screen prequel to the wild television comedy series Strangers with Candy (2005); and Rhonda in Marc Lawrence's romantic comedy Music and Lyrics (2007), co-starring Drew Barrymore and Hugh Grant. Appearances on The New Adventures of Old Christine and Ugly Betty followed, and in 2009 Johnston began teaching acting classes at New York University. Two years later, she documented her struggles with addiction in her memoir Guts: The Endless Follies and Tiny Triumphs of a Giant Disaster.In addition to Johnston's film work, she acts in theatrical productions. Several of Johnston's higher-profiled stage productions include the Scott Elliott-directed revival of Clare Boothe Luce's play The Women (2001, alongside Rue McClanahan, Cynthia Nixon, and Jennifer Coolidge); the Mark Brokaw-directed 2004 production of Paula Vogel's one-act play The Baltimore Waltz (as Anna); and the 2006 John Crowley-directed production of John Kolvenbach's Love Song (as Joan).
