Pornography: A Thriller is a 2009 American mystery/thriller film, written and directed by David Kittredge.

Pornography: A Thriller is a non-linear story in three parts, all revolving around the disappearance of fictional adult gay film actor Mark Anton (Jared Grey). The first act depicts Anton's final days in 1995, the second is about writer Michael Castigan (Matthew Montgomery) as he searches for the truth in 2009 about what happened to Anton, and the third revolves around 2009 adult film actor Matt Stevens's (Pete Scherer) attempt to make The Mark Anton Story, based in part on his dreams of what happened to Anton.

The film uses an unconventional structure, with actors playing multiple roles in different sections, and uses dream logic to tell its story through a subjective point of view. Because of this, it has been compared to the work of David Lynch (most notably Lost Highway and Mulholland Drive) and David Cronenberg (notably Videodrome).

Kittredge says about the structure, "We wanted to replicate the dream logic of a nightmare. So even though we don’t spell everything out for the audience, the film is still a complete whole and has its own fully formed arc that’s hopefully a satisfying whole."
