Trivia: Like many small-screen veterans who headline a hit network series for multiple seasons, the fresh-faced, genial American actor Richard Dean Anderson will forever be associated with one role -- that of Angus MacGyver, the multilingual, crack Special Forces agent and science expert capable of using common household substances and implements to perform feats of wonder, on the Henry Winkler-produced action-adventure series MacGyver. Although Anderson's resumé packs in a number of key telemovies and a recurrent starring role on the popular Stargate SG-1, the actor is best known for turning MacGyver into a veritable American icon for Gen-Xers during the mid- to late '80s and early '90s.Anderson was born on January 23, 1950, in Minneapolis, MN, to a schoolteacher father, Stuart Anderson, who taught English, humanities, and drama at an area high school, and an artist mother. During middle school and high school, Anderson's plans to embark on a career as a professional hockey player were curtailed by two unfortunate accidents in which he broke both arms, encouraging the young man to pursue drama as an alternate option. After high school, Anderson enrolled in both St. Cloud State University and Ohio University, where he studied acting, but -- feeling listless -- he dropped out before receiving his degree, and spent time in San Francisco and Manhattan, then moved permanently to L.A. In Southern California, Anderson held down gigs as a street mime, juggler, and aquatic performer at Marineland, then appeared in the stage production Superman in the Bones at the Pilgrimage Theatre.Aficionados of 1970s American television might recall that Anderson's "breakthrough" arrived not as MacGyver, but as Dr. Jeff Webber on the long-running ABC soap opera General Hospital, circa 1976 -- then in production for 13 years. Not long after two failed series attempts on CBS -- the adventure drama Seven Brides for Seven Brothers in 1982 and the Dennis Weaver-headlined military drama Emerald Point, N.A.S. in 1983 -- Anderson auditioned for Henry Winkler and others to portray MacGyver on that character's eponymous action series. The premise found MacGyver enlisting as a member of a "think tank" called "The Phoenix Foundation," devoted to traveling around the world and thwarting criminal activity. The program's gimmick revolved around scientist MacGyver's abhorrence of guns, and his ability to use seemingly innocent, harmless objects -- such a candy bar, a paperclip, a toothpick, and (of course) his ever-present Swiss Army knife -- to blow up buildings, escape from deathtraps, save lives, etc. Winkler and his co-producers purportedly gave Anderson the part because of his request to wear eyeglasses during the reading -- an act that suggested humility to them and thus meshed perfectly with the character. MacGyver debuted on ABC on September 29, 1985, and lasted seven seasons, retaining a faithful audience despite at least 11 shifts in its night and time slot. It finally wrapped on August 8, 1992. Two telemovies, MacGyver: Trail to Doomsday and MacGyver: Lost Treasure of Atlantis, aired in 1994, both produced by Anderson.Alongside the MacGyver series run and shortly thereafter, Anderson signed for key roles in several network telemovies, including Ordinary Heroes (1985), Through the Eyes of a Killer (1992, which uncharacteristically cast him as a psychotic stalker), Beyond Betrayal (1994), and the epic-length disaster miniseries Pandora's Clock (1996). These proved moderately successful, but Anderson's two additional attempts to produce a network series through his Gekko film production company during the early '90s (Firehouse and Legend) died quick deaths.Anderson nevertheless caught his second wind and returned to series television (garnering a loyal cult following among sci-fi buffs) as Col. Jack O'Neill in the 1997 series Stargate SG-1, which originated on Showtime. Adapted from the hit 1994 movie Stargate, the program found O'Neill emerging from semi-retirement and continually traveling to interstellar "stargate" portals to protect the universe from hostile alien invasions. Stargate SG-1 bowed to extraordinary reviews and ratings and became a permanent hit; Anderson stayed with the series through its eighth season, and appeared as a guest star occationally during the rest of its run. He would go on to appear on the spin off SGU Stargate Universe, as well as the dramedy series Fairly Legal.Though Anderson has never married, he has been romantically linked with such actresses as Marlee Matlin, Deidre Hall, Sela Ward, Teri Hatcher, and Lara Flynn Boyle, and the champion skater Katarina Witt. In 1996, Anderson entered an ongoing romantic relationship with Apryl Prose, and the two had a daughter, Wylie Quinn Annarose Anderson, born in August 1998. Anderson divides his time between residences in Vancouver, Los Angeles, and northern Minnesota.

Trivia: It would be difficult to imagine a more promising or electric series of debuts for a young American actor than those of the fresh-faced, fair-haired Corin "Corky" Nemec, who burst onto the scene as a teenager in the late '80s with several memorable turns that put him on the pop-culture map. Nemec began whimsically, as Nicky Papadopolis -- the nephew of Alex Karras' former football player-turned-sportscaster George Papadopolis -- in the fifth and final, syndicated season of the hit sitcom Webster. That program wrapped by late 1988, but by that time, Nemec had already graduated to feature-film work, with a skillful portrayal of the teenage son of auto mogul Preston Tucker (portrayed by Jeff Bridges), in Francis Ford Coppola's pet project Tucker: The Man and His Dream (1988). Nemec even surpassed this debut one year later, with his haunting portrayal of the sexually assaulted and brainwashed abductee Steven Stayner, in the superior telemovie I Know My First Name Is Steven; it remains a benchmark by which current made-for-television films continue to be judged. Ultimately, however, Nemec gained iconic status among younger Gen X-ers as Parker Lewis, the impossibly sweet-natured but crafty and resourceful high-school student on the Fox network's sitcom Parker Lewis Can't Lose (1990-1993). The program featured bizarre camera angles, accelerated and decelerated action, and wall-to-wall surrealist gags (such as one character's penchant for whipping vanilla frozen yogurts with Gummi bears out of his trench coat). Audiences flocked to it, and kept it on the air for three seasons, while the similarly themed NBC series Ferris Bueller folded within a couple of months. Nemec remained with Parker Lewis for the duration of its run. The program continues to retain a loyal cult following, comprised largely of its initial viewers. Over the years following this program, Nemec alternated between occasional roles on such hit series as NYPD Blue, Beverly Hills 90210, and Smallville, and bit parts in innumerable telemovies and big-screen features -- though none even came close to matching the high profile or notoriety of Lewis. Though an extremely versatile actor, equally adept at comedy and drama, Nemec gravitated most heavily toward direct-to-video and made-for-television horror pictures in the early 2000s. He was particularly memorable in John Badham's made-for-television crime thriller Brother's Keeper (2002), as a mentally troubled child-abuse victim.

Trivia: Hardworking Vancouver-born actor Aaron Douglas launched a successful television career with appearances on such hit shows as Dark Angel, Smallville, Stargate SG-1, and Taken before making the transition into features with roles in the big-screen sequels Final Destination 2 and X2, though it was his role on the hit sci-fi series Battlestar Galactica that truly propelled his career into hyperdrive. Douglas studied his craft at the esteemed William Davis Centre in Canada before joining the Okanagan Shakespeare Company, and it didn't take long for the prominent stage performer to segue into film and television. Supporting roles in such films and TV series as I, Robot, The Chronicles of Riddick, Catwoman, Andromeda, and The Dead Zone endeared Douglas to sci-fi and fantasy fans, and in 2003 he did his best to defend the human race as dedicated deck chief Galen Tyrol on Battlestar Galactica. He remained on Battlestar Galactica until 2009.

Trivia: Supporting actor Peter DeLuise, onscreen since 1987, is the son of actor Dom DeLuise.

Trivia: Dreamed of playing professional hockey as a teen. Studied business in college but switched to theater after failing a calculus course.

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. Played hockey on the Stargate SG-1 team that competed against other productions, such as Smallville, that also shot in British Columbia.

Trivia: The handsome and sturdy Hispanic-American actor Alexis Cruz chalked up an impressive array of bit and supporting roles from the 1980s onward -- mainly in A-list Hollywood features, and usually of an ethnic nature. He appeared very briefly as Charlie in James Toback's woefully underrated freewheeling comedy The Pick-Up Artist (1987), with Robert Downey Jr. and Molly Ringwald, and -- that same year -- played an equally small role in Arthur Hiller's female "buddy comedy" Outrageous Fortune, starring Shelley Long and Bette Midler. Cruz survived enlistment in a couple of ugly and unmemorable productions, including the 1988 family-oriented telemovie Gryphon and the 1989 Robert Wise musical Rooftops, then shifted gears somewhat and made a fast track for the small screen. On television, Cruz is probably best known as Skaara and Klorel on Stargate SG-1; his resumé also includes guest spots on such blockbuster series as NYPD Blue and ER and more prominent roles on Touched by an Angel and American Family. In 2006, Cruz received one of his highest billings to date as the impossibly hip and street-smart Martin Allende, a member of attorney Sebastian Shark's (James Woods) legal team.

Trivia: Argenziano, a supporting actor, appeared onscreen from the '70s.
