Cinema releases
Besides a re-edited version of the pilot, released originally in Canada, Europe and parts of Latin America and, following the broadcast of the series, in the U.S., two other Battlestar Galactica feature films were released in cinemas. Both Mission Galactica: The Cylon Attack and Conquest of the Earth were made up of various episodes of the original series and Galactica 1980 respectively.

Attempted revivals
The original series maintained a cult fandom, which has supported efforts by Glen A. Larson, Richard Hatch, and Bryan Singer (independent of each other) to revive the premise.

Richard Hatch produced a demonstration video in 1998–1999 which featured several actors from the original series combined with state-of-the-art special effects. This video, titled Battlestar Galactica: The Second Coming, was displayed at science fiction conventions, but did not lead to a new series.

In 1999, Wing Commander producer Todd Moyer and original series producer Glen A. Larson revealed plans to produce a motion picture based on the television series It would have featured Battlestar Pegasus.

In 2000, the director and an executive producer of the X-Men film, Bryan Singer and Tom DeSanto, began developing a Galactica television miniseries with Studios USA for FOX. Intended to air as a backdoor pilot in May 2002, filming was scheduled to begin in November 2001.However, production delays caused by the September 11, 2001 attacks meant Bryan Singer had to drop out, due to his directing commitments on X-Men 2. This led Fox to lose interest in the project.

2003 re-imagining

Despite attempts to revive the series over the years, none came to fruition until it was reimagined in 2003 by Universal Television in association with Sky One and the Sci Fi Channel with Ronald D. Moore as the creative force behind it. Edward James Olmos stepped into the role of Commander Adama. A weekly new Galactica series followed, premiering on Sky One in the UK and Ireland in October 2004, and on Sci-Fi in the U.S. in January 2005.
