Trivia: The quiet yet dynamic screen presence of actor Joe Mantegna has made him one of the most powerful supporting actors in Hollywood. Born in Chicago, Mantegna made his acting debut in the 1969 production of Hair. He then joined Chicago's Organic Theatre Company. In 1978, he debuted on Broadway in Working; he also helped write Bleacher Bums, an award-winning play. Still, he did not become well-known until he played a recurring role on the TV show Soap. By 1983 he'd returned to Chicago, where he began working with playwright David Mamet. While playing the lead in Mamet's play Glengarry Glen Ross (1983), Mantegna won a Tony. When Mamet began making films, Mantegna became his actor of choice in works such as House of Games (1987) and Homicide (1991). Prior to that, the actor had played small roles in a number of other films. He also continues to play in a variety of movie genres, working with some of Hollywood's top directors. Mantegna turned producer in 1998 with the crime comedy Jerry and Tom. That trend continued on the small screen as Montenga produced such shows as Midway USA's Gun Stories, Shooting Gallery, and QuickBites, but it was his role as a regular on the CBS series Joan of Arcadia that really kept him in the public eye. Continually returning to his recurring role as Fat Tony on The Simpsons over the next decade, Montegna joined the cast of the hit television series Criminal Minds in 2007, and recieved an Emmy nomination for his performance in the successful mini-series The Starter Wife that same year.

Trivia: Versatile as well as tall, dark, and handsome, Thomas Gibson has moved easily between TV stardom and a varied movie career working with some of the industry's major names. Born and raised in Charleston, Gibson found his calling as a child, making his acting debut at age ten in children's theater productions. Though he attended the College of Charleston, Gibson relocated when he won a scholarship to New York's prestigious Juilliard School. After earning his B.F.A., Gibson made his professional New York theater debut in 1985. Gibson spent the rest of the 1980s doing theater, as well as branching out into television with two seasons on the daytime drama Another World and the TV movie Gore Vidal's Lincoln (1988).Gibson made the transition to films in style with a co-starring role opposite Tom Cruise and Nicole Kidman in Ron Howard's glossy Irish-American epic Far and Away (1992). Along with playing a bit part in Martin Scorsese's lush The Age of Innocence (1993), Gibson further distinguished himself that year with larger roles in the critically praised PBS miniseries Armistead Maupin's Tales of the City and French-Canadian director Denys Arcand's first English-language film, the contemporary drama Love and Human Remains (1993).Gibson subsequently appeared in the second part of Whit Stillman's preppy trilogy, Barcelona (1994), and in the indie Sleep With Me (1994), but he became better-known to TV audiences that year on the CBS hospital drama Chicago Hope. After three seasons on the show, Gibson became an even more prominent TV presence in 1997 when he was cast as the straight-laced husband Greg to Jenna Elfman's hippie Dharma on the ABC sitcom Dharma and Greg. In addition to the memorable role of Greg, Gibson would appear in a number of feature films, like Eyes Wide Shut, The Flintstones in Viva Rock Vegas, and Psycho Beach Party, as well as subsuquent TV series, like the the proceedural Criminal Minds.

He soon followed that performance with a starring role in the series Criminal Minds, playing the young genius Dr. Spencer Reid. He also made a small appearance in the comedy RV before signing on to appear in The Great Buck Howard.

She went on to a recurring role on Higher Ground, a Fox Family Channel series about teens in boot camp, where she played the love interest of fellow Canadian Hayden Christensen prior to his role of Anakin Skywalker in Star Wars: Episode II -- Attack of the Clones. After another TV movie and the snowboarding comedy Out Cold, Cook found her niche as a lead actress in horror movies with Ripper: Letter From Hell in 2001. She then headlined a number of other thrillers, including Wishmaster 3: Beyond the Gates of Hell, The House Next Door, and Final Destination 2.

Trivia: Launching her performing career in her native Tulsa, Jeanne Tripplehorn spent several years as a local radio DJ and TV host. Educated at both the University of Oklahoma and Juilliard, Born June 10th, 1963, Tripplehorn was first seen on a nationwide basis in 1991 in a supporting role in the made-for-TV movie The Perfect Tribute, a fictionalized retelling of the events leading up to Lincoln's Gettysburg Address. Many of Tripplehorn's film characterizations have ranged from mildly eccentric to deeply disturbed, thanks in great part to her breakthrough appearance as Michael Douglas' "rough sex" partner in the erotic chiller Basic Instinct (1992). She got a chance to play normal -- albeit frazzled -- as Hugh Grant's fiancée in the romantic comedy Mickey Blue Eyes (1999); in 2000, she returned to rougher territory as a lesbian gangster in Mike Figgis' experimental ensemble film Timecode.

Trivia: Brad Dourif is a quirky character actor whose gallery of killers, sociopaths, and other lost souls brought to life any number of contemporary horror and science fiction projects. Born March 18, 1950, in Huntington, WV, he began his professional acting career after graduating from college, honing his skills during a three-year apprenticeship with New York's Circle Repertory under the celebrated drama coach Sanford Meisner. While appearing off-Broadway in a production of When You Comin' Back, Red Rider?, Dourif was spotted by director Milos Forman, who immediately cast him in his 1975 film adaptation of the Ken Kesey novel One Flew Over the Cuckoo's Nest. Dourif's turn as a suicidal teen asylum inmate was one of the most acclaimed film debuts in memory, earning a Best Supporting Actor Golden Globe as well as an Oscar nomination. However, the performance also typecast him as a talent best suited to idiosyncratic, off-center character roles, a straitjacket he remained unable to break from for the duration of his career. He then did not reappear onscreen for another two years before co-starring in the 1977 West German production Gruppenbild mit Dame. Dourif's next major performance came in the 1978 Irvin Kershner thriller The Eyes of Laura Mars, followed by a superb starring turn as a damaged war veteran in John Huston's Wise Blood. Upon completing a supporting role in the 1980 television film Guyana Tragedy: The Story of Jim Jones, Dourif next surfaced in Michael Cimino's legendary flop Heaven's Gate, the first in a string of big-budget disasters to which the actor was attached including Forman's Ragtime and David Lynch's Dune. A series of low-budget projects followed before Dourif reunited with Lynch for a small role in the director's 1986 masterpiece Blue Velvet. However, no other offers of a similar caliber were immediately forthcoming, and instead he found himself providing the voice of the evil doll Chuckie in the Child's Play series of slasher movies. In the years which followed, Dourif occasionally reappeared in more substantial projects (including the 1988 Alan Parker film Mississippi Burning, the 1990 Ken Loach picture Hidden Agenda, and Hanif Kureishi's 1991 directorial debut London Kills Me), but he remained primarily confined to low-budget genre work; additionally, he often guest starred on television, appearing in series including The X-Files, Millennium, and Star Trek: Voyager. In 2001, Dourif took a break from low-budget fright flicks to appear in a decidedly more enormous production, director Peter Jackson's eagerly anticipated Lord of the Rings trilogy.

Trivia: Born September 18th, 1970, actress, comedian, author, reality-show host, and occasional scriptwriter Aisha Tyler came of age in San Francisco and studied poly sci at Dartmouth College before mounting a (brief) career as an advertising executive in her hometown. Dissatisfied by this pursuit, and pining to launch herself as a full-time entertainer, Tyler "dropped out" of the corporate world and hit the road with a solo standup comedy act in the mid-'90s.Around 2001 -- after five years in Los Angeles with occasional standup bookings and concomitantly limited acclaim and recognition -- Tyler landed two huge breaks, first as the host of the irreverent Talk Soup during that program's final year (a position she inherited from Greg Kinnear, John Henson, and others), and then as the primary host of the dating series The 5th Wheel. Riding the crest of popularity generated by reality television during the first several years of the millennium, Wheel coupled the unscripted spontaneity of The Real World and Survivor with the format of the dating series Blind Date. Its premise involved setting two couples up on blind dates, having them "swap" partners, and adding an unforeseen fifth member (the "wheel" of the title) to stir things up and add provocation. The program placed a greater emphasis on erotic and suggestive content than Blind and -- perhaps as a result -- it unsurprisingly became a massive, runaway hit.The ever-ambitious Tyler, however, continued to expand her horizons. She maintained a short tenure with Wheel and quickly moved on to other endeavors, placing a particularly strong emphasis on television work. This included a stint as Charlie (the only recurring African-American cast member) in the final two seasons of the popular sitcom Friends, and a recurring role as covert terrorist Marianne Taylor on the weekly suspenser 24. Tyler also portrayed attorney Andrea Moreno (who dies in a car crash but is then "ushered" over to the other side by Jennifer Love Hewitt's psychic) in the first season (2005-2006) of the supernatural drama The Ghost Whisperer. After that, Tyler segued into feature-film work, with bit roles in such pictures as The Santa Clause 3 and .45.Six feet tall and one of the most physically breathtaking young actresses of her generation, Tyler frequently provides beauty tips in such magazines as Ebony and Glamour; she is also an outspoken proponent of physical fitness and a strenuous exerciser who pushes herself to an almost unimaginable degree. A February 2007 issue of In Style magazine reported, "In addition to scaling walls, Tyler runs, uses a rowing machine, lifts weights, snowboards and scuba dives. But for her, nothing beats the mental rush of rock climbing." In 2004, Tyler also authored and published the best-seller Swerve: Reckless Observations of a Postmodern Girl, a free-form, witty expostulation on such "hot" topics as men, bikini waxing, reality television, dating wars, sex, and body image.After filming several unremarkable movies throughout the mid-2000s, the actress found success on Archer, a television series that features Tyler as a dedicated but deadly agent for ISIS, a secret intelligence unit in New York City. While she continued work on Archer, she landed the job of co-host on The Talk, and later, host of the revamped Whose Line Is It Anyway? As if that weren't enough, Tyler also landed a recurring role on Criminal Minds in 2015.
