Jack Plotnick began his acting career in strictly comedic roles, doing guest spots on established sitcoms such as "Murphy Brown," "Seinfeld," and "Ellen. " He has a penchant for the offbeat also, as Plotnick has appeared in such cult favorites as the satirical Möbius strip of a sketch comedy "Mr. Show" with Bob Odenkirk and David Cross, and the frothily followed fantasy saga "Buffy the Vampire Slayer," on which he portrayed the skittish Deputy Mayor Allan Finch throughout its third season. His recurring weirdness as Steve Marmella on the law-enforcement parody "Reno 911!" landed him a regular role as the voice of the mincing video-game character Xandir P. Whifflebottom on another one of Comedy Central's hits, the animated "Drawn Together." He has branched out to drama in the 2000s with roles on such hour-long series as "Dawson's Creek," "House M.D.," and "The Mentalist." Plotnick established himself as an executive producer (and self-made star) with the comedically cross-dressing short-film series "Girls Will Be Girls." He also runs an actors' workshop in Los Angeles and occasionally New York City.
