Where raunchy "South Park" creators Trey Parker and Matt Stone go, Dian Bachar surely isn't far behind. The young actor met the pair while in attendance at University of Colorado at Boulder, and has collaborated with them on nearly all their creative endeavors. The three first teamed as students to produce "Cannibal! The Musical," a grisly send-up of classic Hollywood musicals. Their next major effort was the controversial 1997 sex comedy "Orgazmo," in which Bachar played sidekick to Parker's eponymous Mormon superhero. That same year, "South Park" made its triumphant debut on the cable network Comedy Central, and the pair once again commissioned Bachar, this time to contribute voice work to their mega-popular series. With the success of the show, Parker and Stone were more in vogue than ever, and when the pair were signed to star in David Zucker's sports satire "BASEketball," Bachar stepped in as the comedic punching bag Squeak Scolari. Bachar, removed from his storied friendship with Parker and Stone, also served as a timid technician in the 1999 sci-fi lampoon "Galaxy Quest," though many of his scenes were cut for the theatrical release. Elsewhere, he became a recurring character on the ABC sitcom "Two Guys, a Girl and a Pizza Place," appearing as the stout Roger in four episodes between 2000 and 2001.
