Prisoners of Gravity was a Canadian public broadcasting television news magazine program that explored speculative fiction — science fiction, fantasy, horror, comic books — and its relation to various thematic and social issues. Produced by TVOntario, the show was the brainchild of former comic retail manager Mark Askwith, writer Daniel Richler, and was hosted by Rick Green (of The Frantics comedy troupe fame). The series aired 139 episodes over 5 seasons from 1989 to 1994.

In each episode Rick would interview a number of authors and artists, along with filmmakers, animators and the occasional futurist. Topics that were discussed ran the gamut: censorship, superheroes, humour, religion, fairy tales, Mars, cyberpunk, war, overpopulation, sex... Episodes were 30 minutes in length (having no commercial breaks on public television) and typically showcased six to fourteen interviewed creators alongside bridging commentary from Rick. Roughly six-hundred interviews were conducted and aired by the time the show's run came to an end.

During its run, the list of authors interviewed became increasingly prestigious, including Ray Bradbury, William Gibson, Harlan Ellison, Anne Rice, Frederik Pohl, Clive Barker, David Brin, Charles de Lint, Robert J. Sawyer, Spider Robinson and Terry Pratchett, to name a few. Among the many interviewed comic book creators were Stan Lee, Jack Kirby, Will Eisner, Bob Kane, Frank Miller, Chris Claremont, Scott McCloud, Alan Moore, and Neil Gaiman (who was twice selected as the fan-favorite guest in a viewership mail-in vote). Other notable guests included Star Trek creator Gene Roddenberry and actor Michael Dorn, film directors James Cameron and David Cronenberg, award-winning CGI animator Steve 'Spaz' Williams, and renowned paleontologist Richard Leakey.
