Trivia: Like other Saturday Night Live alumni, Julia Louis-Dreyfus made the move to feature films, but she achieved true stardom on TV as Seinfeld's inimitable Elaine Benes. Born to an affluent family and raised in Washington, D.C., Louis-Dreyfus studied theater at Northwestern University. Along with working as a member of The Practical Theater Company, Louis-Dreyfus cut her sharp comic teeth as part of Chicago's Second City troupe. She soon followed in the footsteps of prior Second City-ers John Belushi and Bill Murray, joining the cast of NBC's Saturday Night Live from 1982 to 1985 (along with Northwestern classmate and eventual husband Brad Hall). Louis-Dreyfus bounced to films with appearances in Soul Man (1986), Woody Allen's Hannah and Her Sisters (1986) and National Lampoon's Christmas Vacation (1989), before returning to TV on the second episode of a low-rated NBC primetime sitcom starring comedian Jerry Seinfeld in 1990.As Jerry's ex-girlfriend-turned-pal Elaine, Louis-Dreyfus proved that she could hold her own as the sole female member of Seinfeld's do-nothing quartet of neurotic New Yorkers. With her "big wall of hair," signature shoes and penchant for over-enthusiastic exclamations, Louis-Dreyfus' Elaine was no mere foil, but rather a full participant in the show's increasingly popular, irony-laden comic shenanigans. Along with winning an Emmy for Best Supporting Actress in a Comedy Series in 1996, Louis-Dreyfus won the Golden Globe in 1994 and the Screen Actor's Guild award in 1997 and 1998. During Seinfeld's phenomenally successful nine-year run, Louis-Dreyfus also played supporting roles in North (1994), Father's Day (1997), and as a libidinous sister in Woody Allen's Deconstructing Harry (1997). After Seinfeld went off the air in 1998, Dreyfus took some time off from appearing in front of the camera to spend time with her husband and two sons, but she did the voice of Princess Atta in the Pixar animated blockbuster A Bug's Life (1998).Louis-Dreyfus subsequently returned to TV as the Blue Fairy in the TV movie musical Gepetto (2000) before attempting another sitcom. After two of her Seinfeld co-stars failed to make their own series fly in 2000 and 2001, Louis-Dreyfus opted for a non-traditional approach, playing a struggling lounge singer in the real time, laugh track free Watching Ellie in 2002. Louis-Dreyfus would continue to remain one of the most beloved comedic actresses in TV, starring on The New Adventures of Old Christine, and the political satire Veep.

Trivia: Clark Gregg has spun a successful career on the New York stage into a growing profile in motion pictures and television as an actor, writer, and director. Clark Gregg's career as an actor began when he was a student at New York University, where he became a protégé of noted playwright and director David Mamet. Mamet cast Gregg in his first film role -- a small part in 1988's Things Change -- and that same year he made his off-Broadway debut in Howard Korder's play A Boy's Life. With Mamet's help, Gregg co-founded the esteemed Atlantic Theater Company in New York in the late '80s, and in 1990, Gregg made his Broadway debut in Aaron Sorkin's drama A Few Good Men. Through the 1990s, Gregg gave a number of strong supporting performances in such films as Clear and Present Danger, The Usual Suspects, and Magnolia, with Gregg earning a Best Supporting Actor nomination at the Independent Spirit Awards for his striking turn as a transsexual in the independent feature The Adventures of Sebastian Cole. In television, Gregg scored recurring roles on the shows The Commish and Sports Night, as well as guest appearances on Sex and the City and The West Wing. And he remained a near-constant presence on the New York stage, earning Outer Critics Circle, Obie, and Drama Desk nominations for his work. Gregg also began directing for the stage, including well-received productions of Mamet's Edmond and Kevin Heelan's Distant Fires. In the late '90s, Gregg developed an interest in screenwriting, and began working on a supernatural thriller in his spare time. As chance would have it, Gregg's script came to the attention of Robert Zemeckis, who was eager to direct a thriller; Gregg's first screenplay became What Lies Beneath, which starred Michelle Pfeiffer and Harrison Ford, and became a major box-office success. He continued to work in a variety of indie and big-budget films including Lovely & Amazing, the Steven Spielberg sci-fi film A.I., Spartan, and In Good Company. In 2006 he landed a recurring role on the well-respected CBS sitcom The New Adventures of Old Christine. He became part of the Marvel universe when he took the part of Agent Coulson in Iron Man, a role he would return to in different comic-book adaptations. He returned to screenwriting and directing with the 2008 adaptation of Chuck Palahniuk's novel Choke. His steady acting career continued with the indie hit (500) Days of Summer and Mr. Popper's Penguins.

Trivia: The son of famed acting instructor and vocal coach Kristin Linklater, character actor Hamish Linklater cut his professional chops on the stage before moving into filmed work. Hamish commenced his professional training with Shakespearean roles before the age of ten, and after his secondary school education enrolled at Amherst College in Boston. Key theatrical assignments following graduation included a part in a production of Cyclone at Studio Dante and a role opposite Jill Clayburgh in The Busy World Is Hushed at Playwrights Horizons. Meanwhile, Linklater stepped in front of the cameras for a multi-episode turn on American Dreams (2004) and a regular role, as Dr. Bruce Cherry, a physician in a Boston teaching hospital, on Gideon's Crossing (2000). The actor also signed for parts in Hollywood features including the telemovie Live from Baghdad (2002) and the theatrical release Fantastic Four (2005), as well as a regular role in the cast of the Julia Louis-Dreyfus CBS sitcom The New Adventures of Old Christine, playing Matthew, the brother of the recently divorced title character (Louis-Dreyfus). When Christine came to an close, Linklater starred in a pair of well-respected indie films, The Future and Lola Versus, before appearing in the would-be mega-blockbuster Battleship.

Trivia: A native of Thousand Oaks, CA, Trevor Gagnon expressed serious interest in a professional acting career from the tender age of six, which prompted his parents to guide him to agency representation. He landed covetable roles in the Tim Burton fantasy Big Fish (2003) and the HBO period drama Iron Jawed Angels (2004), then -- after a lengthy series of commercial spots and commercial auditions -- signed for a role as the son of a single mom played by Seinfeld alum Julia Louis-Dreyfus on the CBS sitcom The New Adventures of Old Christine (2006), and voiced a character in the CG-animated feature Fly Me to the Moon 3-D (2008). Gagnon then signed for a small supporting role in Robert Rodriguez's family-oriented fantasy Shorts, about a little boy who gets everything he wishes for after being conked on the head.

Trivia: American actress Helen Slater was trained at New York's High School for the Performing Arts. In 1984 she was signed for the leading role in Supergirl, perhaps hoping that this modest special-effects fest would do for her what Superman did for another unknown, Christopher Reeve. Alas, Supergirl was a failure, not so much due to Slater's spunky but antiseptic performance as to an uninvolving script and lackluster direction. Since Supergirl, Slater has been seen to best advantage in supporting parts, notably the sweet-tempered kidnapper in Ruthless People (1986) and cattle-drive novice Bonnie Rayburn in City Slickers (1991). In the decades to follow, Slater would appear in numerous projects, but found particular success with roles on the TV series Gigantic and The Lying Game.
