Memphis native Steven Williams has never reached leading man status, and he's most likely the type of actor whose face is more recognizable than his name--but few actors in Hollywood have built resumes as diverse. Williams' first two roles came in mid-70s Blaxploitation films: the comedies "Cooley High" and "The Monkey Hu$tle," and as the years progressed, he also found decent side parts in a number of high-profile projects, including the legendary music comedy "The Blues Brothers." But Williams saved his best work for television--in 1985, he landed a six-episode role on the crime-drama "The Equalizer," and his all-around acting breakthrough arrived in 1987, when he signed on with the cast of the popular crime-mystery series "21 Jump Street," in which he co-starred as Captain Adam Fuller (along with Holly Robinson Peete and a young soon-to-be-megastar Johnny Depp). From that point forward, Williams worked almost exclusively on the small screen; when he wasn't guest-starring on individual episodes of comedies ("The Bernie Mac Show") or police procedurals ("NYPD Blue," "The District"), Williams found himself raking in longer, more noteworthy roles on diverse programs that include the sci-fi classic "The X-Files," the short-lived action-drama "L.A. Heat" (on which he co-starred), and the horror-fantasy "Supernatural."
