Marc Wallice (born Marc Stephen Goldberg October 3, 1959) is a former American pornographic actor in adult films. He tested HIV positive in 1998 after allegedly hiding his HIV positive status for two years and infecting several women, sending shock waves throughout the porn industry. He left the industry but later returned as a director, editor, and writer.
Wallice entered the porn industry in 1982 at the age of 22. He was working as a grocery store bagger when he answered an ad for the World Modeling Agency. He started out with non-speaking roles, but worked his way up to become a very active actor, doing more than 1,300 heterosexual and gay porn movies. He has appeared in many anal sex-oriented films, including Erica Boyer's educational film The Fine Art of Anal Sex/Anal Intercourse, in which he demonstrates basic anal-sex techniques.
He appeared as Don Webber in his only commercially-available gay porn film, A Matter of Size (Huge Video, 1983, Matt Sterling, director), a film that also featured Peter North. In the movie, he performed oral and anal sex in both the top and bottom roles with Scott Avery and Brian Michaels. However, he has also been involved in a series of photo shoots that involve him, Debi Diamond and assorted males in a series of threesomes in which he and Diamond both have sexual contact with men, and Diamond pegs both Wallice and the other males who participate.
