Trivia: Solidly built American actor Craig T. Nelson started out as a comedy writer and performer, doing radio and nightspot gigs in the Los Angeles area. Success was not immediately forthcoming, and Nelson took a four-year sabbatical from show business, moving with his family to a remote cabin in Northern California. In 1979, he made his first film, ...And Justice For All, written by his onetime partner Barry Levinson. While subsequent roles in Poltergeist and Silkwood followed, Nelson would find true stardom on television. For eight seasons beginning in 1989, he starred as college athletics instuctor Hayden Fox on the top-ranked ABC sitcom Coach. Appearing alongside supporting players Jerry Van Dyke and Shelly Fabares, Nelson received an Emmy for his work on the show in 1992.After Coach, Nelson showed up in a few small roles in feature films and television mini-series before returning to series work in 2000, leading the cast of CBS's D.C.-based cop-drama The District. While enjoying the success of that show, Nelson found time for his first high-profile feature film role in over a decade, providing the voice of the head of a family of superheroes in the 2004 Disney/Pixar animated film The Incredibles. In 2005 he played the patriarch of the dysfunctional clan in The Family Stone, and followed that up two years later as skating coach in the comedy Blades of Glory.

Trivia: The son of an editor for the New Yorker, the diminutive comedic actor Wallace Shawn achieved immortality for his portrayal of the Sicilian Vizzini in the 1987 classic The Princess Bride. A graduate of both Harvard and Oxford University, he has taught several courses in English and struggled as a playwright in the early '70s; in 1977 he translated Machiavelli's The Mandrake. Shawn broke into films soon after, building a successful career as a supporting actor to help fund his playwriting. He debuted in two of the best films of 1979: Woody Allen's Manhattan and Bob Fosse's All That Jazz.In 1981, he co-wrote the semi-autobiographical My Dinner With André, a talky comedy starring himself and theater director André Gregory in a dinner conversation, directed by Louis Malle. The movie was acclaimed by critics and a cult favorite. After this personal project, Shawn would build a career out of playing brief but surprisingly memorable roles in a long list of movies. His performance as the leader of the misfit criminal gang in The Princess Bride proved a pivotal moment, and that same year, he supplied the heroic voice for the Masked Avenger in Woody Allen's Radio Days. Shawn would also go on to do voice acting in projects like The Goofy Movie, All Dogs Go to Heaven, and the Toy Story series. He would also continue to work with Woody Allen throughout the next decade, and picked up a new generation of fans playing debate teacher Mr. Hall in the 1995 high school classic Clueless. Shawn would also take his quirky persona to the small screen with appearances on TV shows likeMurphy Brown, The Cosby Show, Star Trek: Deep Space Nine, Sex and the City, as well as the ABC sitcom version of Clueless. Throughout his acting career, Shawn has managed to continue writing successful plays, and eventually adapted one of them, The Designated Mourner, for a feature film in 1997. In 2002, he played the publishing boss Mr. Gelb for the "Greta" story in Rebecca Miller's Personal Velocity: Three Portraits. Shawn would continue to appear regularly on screen in the years to come, playing recurring roles on The L Word, Gossip Girl, and Eureka,

Trivia: A master of improvisational comedy, tall, rangy, and rubber-faced, Ryan Stiles is best known for playing comic Drew Carey's best friend in the ABC sitcom The Drew Carey Show. Born in Seattle, Stiles entered the entertainment industry as a standup comedian in Vancouver, British Columbia. It was not the career his parents had hoped he would choose, but Stiles managed to make a living for a few years. In the mid-'80s, Stiles switched gears and joined the Second City comedy group in Toronto, renowned for its highly topical and fast-paced sketches. There, Stiles grew adept at improvising; in 1990, he transferred to the Los Angeles Second City troupe and, before long, the six-foot, five-inch redhead was working on television and in feature films. He made his film debut in Rainbow War (1986). Stiles' early television credits include guest-starring roles on Parker Lewis Can't Lose and Mad About You. Outside of The Drew Carey Show, he had his greatest success as a regular on the British improvisational series Whose Line Is It, Anyway?, which found an American audience on the Comedy Central cable network. During the show's run (1988-1993), it won four CableACE awards. The show was revised and updated, as a replacement series on ABC, in the summer of 1998. The show was hosted by Drew Carey.

Trivia: A Chicagoan from head to toe, American comedian Bob Newhart started his workaday life as a certified public accountant after flunking out of law school. As a means of breaking his job's monotony, Newhart would call his friend Ed Gallagher, and improvise low-key comedy sketches. A mutual friend of Newhart and Gallagher's, Chicago deejay Dan Sorkin, tape-recorded some of these off-the-cuff routines and played them for Warner Bros. records. Newhart suddenly found himself booked into a Houston nightclub -- his first-ever public appearance. Armed with telephone-conversation routines which delineated how Abe Lincoln would be handled by a publicity agent, or how Abner Doubleday would have fared trying to sell baseball to a modern-day novelty firm, Newhart recorded his first comedy album in 1960 -- which evidently struck a nerve with fellow white-collar workers, since it sold 1,500,000 copies. The hottest young comic on the club-and-TV circuit, Newhart was offered starring roles in situation comedies, but felt he wasn't a good enough actor to make a single character interesting week after week. Instead, he signed in 1961 for NBC's The Bob Newhart Show, a comedy-variety series which nosedived in the ratings but won an Emmy. Fearing that TV would eat up all his material within a year or so, Newhart went back to nightclubs after his one-season series was cancelled. Sharpening his acting skills in TV guest spots and in several films (his first, 1962's Hell is For Heroes, was so unnerving an experience that Bob repeatedly begged the producers to kill his character off before the fadeout), Newhart felt emboldened enough to attempt a regular TV series again in 1972. This Bob Newhart Show cast the comedian as psychologist Bob Hartley - an ideal outlet for his "button-down" style of dry humor. Six seasons and several awards later, Newhart was firmly established as a television superstar; this time around he wasn't cancelled, but ended the series on his own volition, feeling the series had exhausted its bag of tricks. Most popular sitcom personalities had come acropper trying to repeat their first success with a second series, but Newhart broke the jinx with Newhart in 1982, wherein Bob played author Dick Loudon, who on a whim decided to open a New England colonial inn. Newhart was every bit as popular as his earlier sitcom, and, like the previous show, the series ended (in 1990) principally because Newhart chose to end it. This he did with panache: Newhart's final scene suggested the entire series had been a bad dream experienced by Bob Newhart Show's Bob Hartley! A third starring sitcom, 1992's Bob, found Newhart playing a cult-figure comic book artist; alas, despite excellent scriptwork and the usual polished Newhart performance, this new series fell victim to format tinkering and poor timeslots. Over teh course of the next few decades, Newhart would frequently turn up in guest roles on shows like Murphy Brown, ER, and Desperate Housewives, and though his 1997 odd couple sitcom George & Leo failed to find its footing, he did appear in all three installments of TNT's popular fantasy trilogy The Librarian, starring Noah Wyle. Meanwhile, cameos in such films as Elf and Horrible Bosses continually offered a gentle reminder that comedy's nicest funnyman could still crack us up.

Trivia: Awarded a Grammy for Best New Artist in 1984, the inimitable Cyndi Lauper has also accumulated a sufficient amount of screen and TV credits. Other than brief cameos in WWF videos during her bizarre wrestling-crossover phase, Lauper's first feature-film venture was in 1985, singing the theme song for The Goonies. She would appear on several other soundtracks throughout the decade (including singing the theme song for Pee-Wee's Playhouse), but her acting debut was in the star vehicle Vibes (1988), which didn't do too well at the box office. Her next leading role was in another flop, Off and Running (1990), where she met her husband, actor David Thornton. She had a small role in the family comedy Life With Mikey in 1993, as well as contributing to the musical score. While she continued to put out albums, she made a few guest appearances on TV shows. In 1995, she won an Emmy award for her role as Marianne on the sitcom Mad About You. It wasn't until her role as Sally in the independent film The Opportunists in 2000 that she got some critical acclaim for her acting performance in a film. She would follow this with a handful of selective appearances on screen over the coming years, playing cameo roles on shows like That's So Raven, and in films like National Lampoon's Dirty Movie.
