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: Forever associated with his ongoing voice work as Homer J. Simpson on Matt Groening and James L. Brooks' long, long-running Fox animated sitcom The Simpsons, Dan Castellaneta is well-reputed for his modest, unassuming presence in real life and his paradoxical ability to spin characters -- seemingly from out of nowhere -- that instantly take on lives of their own. Groening once famously remarked that "Dan can do everything, and he practically does....You might never notice him, but then he opens his mouth and he completely creates one character after another.'' Born in 1957, Castellaneta grew up in the small town of Oak Grove, IL, in the northwestern corner of the state, near the Iowa border. As a self-described introvert who developed and honed a facility for slipping into the guise of characters to entertain and make social situations easier (read: class clown), Castellaneta nevertheless diverged from this path in college and worked toward a career as a high-school art teacher via his studies at Northern Illinois University. Then, one of Castellaneta's professors (perhaps sensing some dissatisfaction) wisely admonished him to only work at a field, and in a job, that he loved. Castellaneta reasoned that acting fit the bill, and auditioned for the infamous sketch comedy troupe Second City shortly after graduation. The troupe hired him, and in time, the skills that the actor projected led to his involvement on the then-fledgling Fox network's sketch comedy series The Tracey Ullman Show, which premiered on Sunday, April 5, 1987. Castellaneta joined Ullman, Julie Kavner, Joe Malone, Sam McMurray, and for a time Anna Levine in live-action skits that parodied all aspects of Western culture.As a most unusual aspect of her program, Ullman opted to feature crudely animated, offbeat segments as Monty Python-style transitions between the individual sketches. The episodes in question were drawn by Gabor Csupo and Groening (at that time, comic-strip artist of growing infamy known for his Life Is Hell series starring a buck-toothed, bug-eyed rabbit named Bucky). Although the subjects of the shorts initially varied, within a few months they began to focus exclusively on a hyper-dysfunctional blue-collar family called the Simpsons; Kavner and Castellaneta voiced parents Homer and Marge Simpson, respectively. Those segments gained such massive popularity that they eventually outshone that of the Ullman show itself (which wrapped in September 1990), and executive producer James L. Brooks, following this cue, decided to spin off the Simpsons into their own weekly animated series. Kavner and Castellaneta, of course, followed Brooks to the new program, joined in time by longtime Brooks acquaintance Harry Shearer, as well as Nancy Cartwright, Yeardley Smith, Hank Azaria, and numerous others.The Simpsons premiered on Fox on December 17, 1989, and became not simply a hit but a phenomenon. It shot up to instantly become one of the highest-rated series on television, and attained iconic status. The program scored as a cause célèbre not simply with children (as expected) but with adult viewers as well, who appreciated the show's ability to skewer all aspects of society and culture. (It generated a billion-dollar marketing boom as well -- an onslaught of Bart Simpson-themed T-shirts, watches, dolls, beach towels, and everything else under the sun.) The program also drew an onslaught of celebrity guests -- everyone from Larry King to Tony Bennett to Beverly D'Angelo and Linda Ronstadt. Castellaneta himself will forever be tied to Homer Simpson -- the lunkheaded, potbellied, beer-swilling, donut-loving nuclear-plant worker with not a whole lot upstairs, and a thoroughly crass lifestyle, but also a big, soft heart (a quality which Castellaneta's co-workers insist that he alone brought to the character). But hardcore Simpsons cultists and even its less attentive devotees will realize that Castellaneta voices not only Homer (as mentioned), but also the gravelly voiced, booze-swilling, womanizing clown Krusty; local drunk Barney Gumble; Scottish elementary-school groundskeeper Willie; the octogenarian family patriarch Grampa Simpson; and innumerable others. Certainly, it would be difficult to imagine a program that took fuller advantage of Castellaneta's versatility with characterizations.Alongside The Simpsons, Castellaneta has also pursued a career as a live-action film and television performer, and spent most of the late '80s, '90s, and 2000s vacillating between the two mediums. His career on the big screen began at least a year prior to his involvement with Ullman and co., when he debuted with a bit part as Brian in the now-forgotten Garry Marshall dramedy Nothing in Common (1986), starring Jackie Gleason, Tom Hanks, Eva Marie Saint, and Sela Ward. In 1989, Castellaneta landed bit parts in two wildly different films: one as a maître d' in the Jim Belushi cop comedy K-9, and another (as one of Danny DeVito's clients) in the James L. Brooks-produced jet-black marital farce The War of the Roses. Castellaneta temporarily withdrew from live-action cinematic work in the early '90s, before returning to audiences as the narrator in Super Mario Bros. (1993) and Phil in Warren Beatty's Love Affair (1994). As the Castellaneta's career continued, he then segued into cinematic animated voice-over work (doubtless encouraged by the ongoing success of The Simpsons), doing voices in such features as 2000's Rugrats in Paris (under the aegis of old colleague Gabor Csupo) and Hey Arnold! The Movie (2002). In 2007, Castellaneta extended his Homer characterization to the big screen with his work on The Simpsons Movie -- the first cinematic appearance of Groening's famous animated family.As for television, Castellaneta appeared as a supporting actor in numerous sitcoms during the 1990s. These included ALF (as Steve Michaels in the 1990 episode "Stayin' Alive"), Married...with Children (as Pete in the 1990 episode "The Dance Show"), Wings (as George Wexler in the 1994 episode "Moonlighting"), and Murphy Brown (as Tony Lucchesi in the 1995 episode "Specific Overtures.") He also voiced Genie (inheriting the role from Robin Williams) on the animated Aladdin TV series. Of the Simpsons cast, Castellaneta is one of the only actors to regularly do on-stage comedic improvisation alongside his series work. He is married to Simpsons writer Deb Lacusta, whom he wed in 1987.He continued to work steadily in animated films such as Rugrats in Paris: The Movie and Hey Arnold! The Movie, and landed traditional acting parts every once in a while in movies as diverse as the indie comedy I Want Someone to Eat Cheese With and the Will Smith drama The Pursuit of Happyness. In 2007 he voiced nearly 20 different parts in The Simpsons Movie. He also landed a part in JJ Abrams 2011 Spielberg-influenced family sci-fi film Super 8.
