RiffTrax

RiffTrax is an American production company specialising in "riffing" existing films.

RiffTrax feature comedians poking fun at films in the form of satirical commentary tracks. The project is a conceptual spinoff of cult television series , and stars former lead actors and writers of that series. Some of their riffs come in the form of audio files the viewer plays in sync with their own copy of the targeted film, avoiding the need for RiffTrax to secure release rights to the film; other RiffTrax releases are full streaming and downloadable Video On Demand releases of the original films with applied RiffTrax commentary, with any necessary release rights secured.

In 2013, RiffTrax released riffed VOD editions of Dr. Who and the Daleks and Daleks' Invasion Earth 2150 A.D.
