[2] As a founding member of The Wooster Group, directed by Elizabeth LeCompte at the Performing Garage in downtown New York, Vawter originated roles in Rumstick Road, Nayatt School, Point Judith (an epilog), Route 1 & 9, Hula, L.S.D.
In addition to his work over 15 years at the Performing Garage, Vawter appeared in films, including King Blank, Philadelphia, The Silence of the Lambs, and Sex, Lies, and Videotape, generally playing character roles.
Vawter explored themes of sexual identity in his 1992 work for the stage, Roy Cohn/Jack Smith, two linked monologues that contrast the characters of two gay men who died of AIDS.
Based on the story about Philoctetes—the ancient Greek warrior whose wound smelled so intolerably noxious that he was banished to the uninhabited island of Lemnos and abandoned by his comrades-in-arms on the way to Troy—it has consequently also become a metaphor for AIDS, with Philoktetes as a plagued outcast.
In director Jan Ritsema's triptych at the Brussels Kaaitheater in 1994, Vawter embodied Philoktetes in three forms, using his own body naked and covered with purple Kaposi rash.
