Trivia: It took versatile actor James Belushi several years to slowly come into his own, which wasn't an easy task following in the fiery footsteps of his flamboyant, self-destructive brother, the late comic John Belushi. Despite that obstacle, the easy-going actor with the crooked smile still managed to forge a respectable career playing co-leads in a variety of film genres, including comedy, action, and drama in roles ranging from a sleazeball thief to a cop to a party animal in a gorilla suit. Prior to his first television appearances, the Chicago-born actor earned a degree in Speech and Theater, and worked on-stage in The Pirates of Penzance and True West. Like John, James joined the notorious Second City improvisational comedy group. He also began making regular guest appearances on Saturday Night Live, where his brother became famous in the mid-'70s. Making his feature film debut playing James Caan's calm partner in 1981's Thief, James Belushi began acting under John Landis (who also directed his brother) in Trading Places (1983). He continued playing supporting roles and occasional leads -- most notably in Oliver Stone's Salvador with James Woods in 1986 -- but his big break came when he played a bad cop in 1988's Red Heat with Arnold Schwarzenegger. He was equally popular in K-9 the following year. Although his subsequent films were not as successful, Belushi continued to grow as a dramatic actor. In 2001, Belushi began headlining the successful ABC sitcom According to Jim.

Trivia: The son of a jazz concert producer, Billy Crystal grew up in the company of such music legends as Billie Holiday, Pee Wee Russell, and Eddy Condon. His mind made up by age five, Crystal knew he wanted to become a performer -- not in music but in baseball or comedy. As he later explained to TV Guide, he chose comedy "because God made me short" -- though from all reports he is one of the best ball players in show business.Learning how to make people laugh by studying the works of past masters Laurel and Hardy, Ernie Kovacs, and Jonathan Winters, Crystal began making the club rounds at 16. He was sidetracked briefly by New York University's film school, where he studied to be a director under Martin Scorsese, but upon graduation it was back to comedy when Crystal formed his own troupe, 3's Company. On his own, he developed into an "observational" comic, humor based on his own experiences and the collective experiences of his audience. He came to media attention via his impression of Howard Cosell interviewing Muhammad Ali. After doing time as an opening act for such musicians as Barry Manilow, Crystal struck out for Hollywood, in hopes of finding regular work on a TV series. In 1977, he was hired to play the gay character Jodie Dallas on Soap. Though many people expected the performer to be typecast in this sort of part, he transcended the "sissy" stereotype, making the character so three-dimensional that audiences and potential employers were fully aware that there was more to Crystal's talent than what they saw in Jodie.Thanks to Soap, Crystal became and remained a headliner and, in 1978, had his first crack at movie stardom as a pregnant man in Rabbit Test. The movie was unsuccessful, but Crystal's star had not been eclipsed by the experience; he was even entrusted with a dramatic role in the 1980 TV movie Enola Gay. His career accelerating with comedy records, choice club dates, regular appearances on Saturday Night Live, and TV guest shots, Crystal had a more successful stab at the movies in such films as This is Spinal Tap (1984), The Princess Bride (1987), Throw Momma From the Train (1987), and When Harry Met Sally (1989). Riding high after a memorable emceeing stint at the Oscar ceremony, Crystal executive produced and starred in his most successful film project to date, an uproarious middle-age-angst comedy called City Slickers (1991). In 1992, he mounted his most ambitious film endeavor, Mr. Saturday Night, the bittersweet chronicle of a self-destructive comedian. The film had great potential (as indicated by the outtakes contained in its video cassette version), but the end result died at the box office. That same year, Crystal again hosted the Oscar awards, and in 1994 he repeated his earlier success with the popular sequel City Slickers 2: The Legend of Curly's Gold.Crystal added to his directing credits the following year with the romantic comedy Forget Paris. Unfortunately, the film -- which he also produced, wrote, and starred in -- was something of a flop. He subsequently focused his energies on acting, turning up in Hamlet (1996) and Deconstructing Harry (1997). In 1998 he had another producing stint with My Giant, a comedy he also starred in; like his previous producing effort, that film also proved fairly unsuccessful. However, Crystal bounced back in 1999, executive producing and starring in Analyze This. A comedy about a mob boss, Robert De Niro, seeking therapy from a psychiatrist (Crystal), it won a number of positive reviews, convincing many that the performer was back in his element.Back in the director's chair in 2001, Crystal helmed the made-for-HBO 61*. Detailing the 1961 home-run race between Roger Maris and Mickey Mantle, 61* struck a chord with baseball sentimentalists and critics alike. Scripting and starring in America's Sweethearts the same year, Crystal also began to cultivate a voice acting career that would prove extremely successful, providing the voices for characters in Monsters, Inc., Howl's Moving Castle and Cars. As the 2010's continued to unfold, Crystal would find himself increasingly able to take the reigns on both sides of the camera, flexing his muscles as a producer and writer as well as actor, such as with the 2012 comedy Parental Guidance.

Trivia: Well-trained in the exacting school of improvisational comedy, Mary Gross was a regular on Saturday Night Live from 1981 to 1985. Her later series-TV credits include the roles of Abigail McIntyre Kellogg in The People Next Door (1989-90) and Phoebe in the 1992 Billy Connolly vehicle Billy. Mary Gross has made many a welcome comic visit to such big-screen fare as Troop Beverly Hills (1988) and The Santa Clause (1994). Actress Mary Gross is the sister of actor Michael Gross, with whom she appeared in the 1988 film Big Business.

Trivia: An alumnus of New York City's High School of Music and Arts and Bard College, actor/writer/director Christopher Guest made his initial Broadway appearance in the 1970 revival of Room Service; two years later, he co-starred in Moonchildren. Guest's early acting accomplishments have tended to become obscured in the light of his extensive work for the National Lampoon folks: he wrote several articles for the Lampoon magazine, and was a writer/performer for the organization's radio programs, record albums, and stage reviews. His extensive comic talents went largely untapped in such "mainstream" acting assignments as the made-for-TV Blind Ambition (1982), in which he portrayed Nixon intimate Jeb Stuart Magruder, and the theatrical feature The Long Riders (1982), in which he was co-starred with his younger brother Nicholas.In 1982, Guest played divorced suburbanite Bucky Frische in Million Dollar Infield (1982), a made-for-TV movie produced and co-written by Rob Reiner. His association with Reiner extended into appearances in the latter's big-screen directorial efforts: In This is Spinal Tap (1983), Guest not only penned the script but also played heavy metal rocker Nigel Tufnel; and in The Princess Bride (1986), cast as the evil Count Rubin, he offered a sly impression of British character actor Henry Daniell. Guest has since parlayed his "Spinal Tap" association into something of a second career, touring as Nigel Tufnel with fellow "Tap" members David St. Hubbins (Michael McKean) and Derek Smalls (Harry Shearer) and composing many of the group's "hits." On TV, Guest was a regular during the 1984-1985 season of Saturday Night Live and shared a scriptwriting Emmy for a 1976 Lily Tomlin special. Making his directorial debut with the Tinseltown satire The Big Picture (1989), Guest has gone on to helm the TV-movie remake of Attack of the 50 Foot Woman (1993), the "Johnny Appleseed" segment of Shelley Duvall's cable-TV anthology American Tall Tales and Legends, and most of the episodes of Rob Reiner's 1992 TV sitcom Morton and Hayes.After once again appearing as Nigel Tufnel in The Return of Spinal Tap (1992), the latter '90s found Guest expanding on his successes in the world of showbiz mockery by taking the directors chair with a few irreverent faux documentaries of his own. Re-teaming with fellow bandmates McKean and Shearer for the musical numbers in Waiting for Guffman (1996), the critically praised comedy proved that Guest's eye for satire was indeed as sharp as his pen. Following with some vocal work in Small Soldiers (1998), Guest returned to the director's chair for what would be comedian Chris Farley's last film, Almost Heroes (1998). Both of these projects proved to be brief diversions, though, and, as old habits die hard, Guest couldn't resist his urges for parody for long.Though not related (in a traditional sense) to show business, Best in Show targeted a subject that some may say was screaming for parody, the world of Championship Dog shows. His skills as a director more focused and refined than ever, Guest lead a talented cast of the usual suspects in creating yet another hilarious and scathing take on a what many considered to be well-deserving subject. After earning a Golden Globe nomination for "Best Comedy" at that year's ceremony, the film went on to live a healthy life on DVD and cable television. Guest's next film set its sights on a target that many may agree was begging for the treatment even more so than that of his last subject, and though A Mighty Wind's spot on folk song parodies would prove almost so effective as to be considered the real deal, the film itself differed from Best in Show in that it sharply divided its supporters and detractors as few of his films had. Guest worked as an actor, screenwriter, songwriter, and director for The Mighty Wind (2003), an award-winning mockuementary chronicling the ups and downs of a career in folk music, and again with For Your Consideration (2006). The actor would co-star with Judi Dench and Bob Hoskins in Mr. Henderson Presents (2005), which followed a wealthy eccentric determined to transform a dingy London theater into a thriving hotspot for entertainment, and take on roles in 2009's The Invention of Lying and Night at the Museum: Battle of the Smithsonian. Guest is married to actress Jamie Lee Curtis.

Trivia: Supporting actor and comedian, onscreen from the '80s.

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: California native Harry Shearer was one of the busier child actors of the 1950s. He appeared in such films as The Robe (1953) (as the boy David) and Abbott and Costello Go to Mars (1953); he could be heard on such radio programs as Suspense, Lux Radio Theatre, and the Jack Benny Show; and among his many TV guest roles was the character who would evolve into Eddie Haskell in the 1955 Leave It to Beaver pilot. After attending U.C.L.A., Shearer flourished as a standup comedian and comedy writer. He was frequently employed on the writing staff for such TV laughspinners as Laverne and Shirley and America 2Night; he also worked both sides of the camera in the 1984 rockumentary parody This Is Spinal Tap, co-starring as rock idol Derek Smalls and co-writing the script with director Rob Reiner and fellow cast members Christopher Guest and Michael McKean. In league with another top satirist, Albert Brooks, Shearer concocted the screenplay for another faux documentary, 1979's Real Lampoon. During the 1984-1985 TV season, Shearer joined the Not Ready for Prime Time Players on NBC's Saturday Night Live. The soft-spoken, saturnine Harry Shearer is most famous however for lending his voice to the Fox Network cartoon series The Simpsons.

Trivia: The son of a steel-executive father and concert violinist mother, Ontario native Martin Short attended McMasters University, where he graduated in 1972 with a degree in social work. If you haven't spotted Short at your local youth center or settlement house, it's because he decided to pursue a performing career, encouraged by his fellow McMasters classmates Eugene Levy and Dave Thomas. Making his professional debut in a 1973 Toronto production of Godspell, Short joined Levy and Thomas at the Second City improv troupe in Edmonton, Alberta in 1977. Two years later, Short made his first film, Lost and Found, and also co-starred on the critically lauded but little-seen American sitcom The Associates. It was while appearing on SCTV Network 90 from 1982 through 1983 and Saturday Night Live from 1984 through 1985 that Short attained stardom with such distinctive comic characterizations as supercilious showbiz promoter Jackie Rogers Jr. and pointy-headed nerd Ed Grimley (this last-named character was spun off into an amusing Saturday morning cartoon series in 1989). He also scored big yocks with his devastating, dead-on impressions of such icons as Jerry Lewis and Katharine Hepburn (a lifelong Jerry Lewis fan, Short was invited to join Lewis as co-host of a cable-TV Martin and Lewis retrospective in 1993; he has yet to share the spotlight with the real Ms. Hepburn). Though an extremely likeable screen presence, the puckish Short has, like many of his Second City brethren, frequently been cast in films far beneath his talents, hitting bottom with 1994's Clifford. Happily, he has been extremely well-served in such films as Three Amigos (1986), Innerspace (1989), and the 1992 remake of Father of the Bride, in which he had an unbearably funny cameo as epicene wedding planner Franck Eggelhoffer. In 1993, Short made his Broadway debut, assuming the old Richard Dreyfuss role in a musical adaptation of the 1977 film The Goodbye Girl. The following year, Martin Short had another go at television, headlining the weekly (but not for long) Seinfeld rip-off The Martin Short Show. Subsequently donning a fat suit as Jiminy Glick in the Comedy Central talk-show parody Primetime Glick, Short skewerd Hollywood ni a way that only an insider could and in 2004 the character took the lead in his own feature -- Jiminy Glick in Lalawood. Meanwhile, guest appearances on Curb Your Enthusiasm, Arrested Development, Damages, Weeds, and How I Met Your Mother kept him busy as ever. Beginnig in 2010, Short voiced The Cat in the Hat in the popular PBS Kids series The Cat in the Hat Knows a Lot About That!, and in 2012 he essayed a variety of wacky characters in the musical comedy I, Martin Short, Goes Home, which found him reunited with a number of his former SCTV co-stars including Joe Flaherty and Eugene Levy.

Trivia: New Zealand-born lead actress, onscreen from 1977.
