Trivia: Dreamed of playing professional hockey as a teen. Studied business in college but switched to theater after failing a calculus course. Was inspired to pursue an acting career after seeing future Stargate SG-1 costar Richard Dean Anderson shoot a scene from MacGyver on a Vancouver beach. Performed at the Stratford Shakespeare Festival for two seasons. Met his wife, Lexa Doig, while guest-starring in an episode of her sci-fi series, Gene Roddenberry's Andromeda.

Trivia: The son of actor Lloyd Bridges, Beau Bridges (born Lloyd Vernet Bridges III) was actually named for his father; the nickname "Beau" was borrowed from Ashley Wilkes' son in Gone With the Wind. Beau received good billing for his secondary juvenile role in The Red Pony in 1949, although he was primarily seen in bit parts during the late '40s. This suited him fine; not all that interested in films, young Bridges had aspirations of being a basketball star. Despite being only 5'9", he played on the U.C.L.A. basketball team and at the University of Hawaii. But realizing that his height would always hold him back in professional sports, Bridges returned to acting via a small role on his father's TV series Sea Hunt. He made his stage debut in 1966's Where's Daddy and continued appearing in leading film roles throughout the 1960s and '70s, easing into character leads. Bridges directed two feature films, The Wild Pair (1987) and Seven Hours to Judgment (1988), in addition to the TV special The Thanksgiving Promise, in which virtually the entire Bridges clan (including his mother Dorothy) was cast. Bridges received Emmy and the Golden Globe awards for his portrayal of the title character in the 1992 TV movie Without Warning: The James Brady Story (1991), and won awards for his participation in the gloriously-titled made-for-cable The Positively True Adventures of the Alleged Texas Cheerleader-Murdering Mom (1993). He would continue to appear prominently both on the big and small screens over the coming decades, on shows like The Agency and Stargate: Atlantis and in films like The Good German and The Ballad of Jack and Rose.

Trivia: Louis Gossett Jr. ranks as one of the most respected African-American actors of stage, screen, and television. Tall, lanky, and bald-pated, Gossett was a basketball player in high school until a leg injury benched him and his interest turned toward acting. In 1953, at the age of 17, Gossett made his Broadway debut in Take a Giant Step, and ended up with a Donaldson Award for the year's best newcomer. Though working steadily on stage and television, Gossett was still interested in basketball. The New York Knicks drafted him out of college in 1958 and he played with them briefly before returning to performing. In 1961, Gossett reprised on film the role he played in the theatrical production of A Raisin in the Sun. It was a well-regarded beginning, and he continued to appear on stage and television, and beginning in 1967, the occasional feature film or television movie. During this early period, he also occasionally sang in nightclubs. Gossett did not become a bona fide star until his Emmy-winning performance in the landmark television miniseries Roots (1977). His career picked up considerably after that. In 1982, Gossett earned a Best Supporting Actor Oscar for playing a deceptively heartless drill sergeant in An Officer and a Gentleman. That same year, he also starred in another television series as the wise mentor to an alien prince in The Powers of Matthew Star (1982-1983). After the success of An Officer and a Gentleman, Gossett reprised his roll as the tough sergeant, albeit using different character names, in several films, including the Iron Eagle series, The Punisher (1989), and others. But though he makes an excellent rough guy, Gossett has showed a willingness to let his softer side show through in such made-for-TV movies as Sudie and Simpson (1990).

Trivia: Enrolled in college, but quit after only three weeks in order to concentrate on acting. An action figure was created for Aeryn Sun, the character she played on Farscape from 1999 to 2003. Won a Saturn Award for Best Actress in 2004 for Farscape: The Peacekeeper Wars. Had a recurring role on ninth season of Stargate SG-1 before joining the cast a series regular for the 10th and final season; she later reprised her role in two direct-to-DVD films.

Trivia: A talented character actor whose pudgy frame and adaptable face allows him to alternate between meek and imposing at the drop of a hat, Maury Chaykin endeared himself to television audiences as razor-sharp detective Nero Wolfe, though he has been appearing in film and television since the late '70s. Raised in Brooklyn, NY, Chaykin took a shine to acting while attending James Madison High School. Following his dream to the University of Buffalo, where he majored in theater, it was there that Chaykin would found The Swampfox Theater in 1968. An avant-garde troupe that became the talk of the town after crashing Toronto's Festival of Underground Theater in 1970, The Swampfox troupe would later gain accolades as the most original group at the Yale Drama Festival. Following such strong beginnings, it was clear to many that great things were in store for Chaykin. Spending a few years at North Buffalo's American Contemporary Theater following his college graduation, Chaykin would later move on to work in experimental theater in Toronto. Alternating frequently between television and film in his early years, small early roles in such popular films as 1983's WarGames insured the burgeoning actor increased visibility, and following roles in such high-profile fare as Mrs. Soffel (1983) and Turk 182! (1984), Chaykin made a lasting impression when promoted to leading-man status in 1985's Canada's Sweetheart: The Saga of Hal C. Banks. Flawlessly essaying the role of a Canadian union-leader who presided over the country's shipping industry in the 1950s and '60s, the film found Chaykin gaining near universal critical accolades in addition to winning a Nellie Award for his spot-on performance. Despite his success in the role of Banks, Chaykin rounded out the '80s with appearances in such schlocky films as Meatballs III (1987) and Iron Eagle II (1988), with only the occasional dark drama such as Cold Comfort (1989) offering the rare opportunity for him to truly shine. Things began to look up for Chaykin in the 1990s, and appearances in such acclaimed efforts as Dances With Wolves (1990) and My Cousin Vinny (1992) ensured that he would retain a high profile in the coming years. Though Chaykin's roles were far from top-billed, appearances in Sommersby (1993) and Devil in a Blue Dress (1995) served well to balance out forgettable turns in such efforts as Josh and S.A.M. (1993). In addition to an affecting turn as a faded rock star who attempts to create music that will allow him to communicate with nature in 1994's Whale Music, a haunting turn in the downbeat drama The Sweet Hereafter (1997) provided Chaykin with one of his most memorable roles of the decade. As the 1990s drew to a close, his turn as a biker inmate in the long-running HBO series Oz found a virtually unrecognizable Chaykin using his imposing frame to surprising effect. Rounding out the decade with roles in Entrapment and Mystery, Alaska (both 1999), it seemed that Chaykin was finally getting the recognition he deserved. At the dawn of the new millennium, television audiences began to warm up to Chaykin when A Nero Wolfe Mystery debuted in 2001. That same year Chaykin would take a memorable turn as a bumbling bureaucrat in director Jonathan Parker's Bartleby, and a dramatic role as a husband suffering after the tragic loss of a child in the made-for-television Crossed Over (2002) proved that he could alternate between mystery, comedy, and drama with unprecedented ease. In the following years, Chaykin could be spotted in substantial roles in such films as Owning Mahowney (2003) and Being Julia (2004).
