Stargate comics are a series of comic books based on the 1994 science-fiction film of the same name, and the TV series Stargate SG-1 (1997–2006) and the spin-off Stargate Atlantis (2004–2009). The initial comics were tie-ins with the film and the later output by Avatar Press has been based on the two TV series. Movie comic sequels A series of Stargate film-related comics were published by the independent publishing house Entity Comics between 1996 and 1997, under the creative direction of John Migliore and Bill Maus.
