For the record, Larson was working on a Battlestar Pegasus movie for about 8-9 months when it became apparent that Universal wasn't going to go anywhere with the Galactica franchise. It turned out that Larson did have the rights through some contractual snafu on Universal's part to do anything with Commander Cain and the Pegasus, and his planned film involved the search for an ancient battlestar called the Atlantis, which was built by the 13th Tribe and deliberately left in a secret location with the maps to Earth. The film would have dealt with the search, a major battle with the Cylons, and the recovery and use of the maps to reach Earth, all w/o involving the Galactica or the RTF other than being mentioned.

The first article Google shows is this one: . And the Wikipedia set up for BSG had this one: [], although I'm not sure about whether there's some Wikirule about referencing other mini-Wikis. The John Larocque article on the attempt is at: []. Hollywood North Report has a short blurb about the Larson effort, but seeing as how their site has a *LOT* of popups from spammers attempting to load trojans and spyware, I'll quote it here to save your systems:
"In the spring of 1999, it was announced that Glen Larson was making plans to bring Galactica to the silver screen.  Impressed with the visual effects and style of the independently financed film Wing Commander, Larson paired with its producer, Todd Moyer, on an estimated $40-50 million film that was to shoot later that year in Luxembourg. 

The story picked up where the series left off, but followed the exploits of Commander Cain and the battlestar Pegasus (made famous in the original series episode, "The Living Legend," guest starring the late Lloyd Bridges).  In the concept, Commander Cain's search for the lost battlestar Galactica leads him to contemporary Earth, which, according to the story, was settled by humans who arrived here during prehistoric times on the very first battlestar, Atlantis.

Special effects were to be handled by Moyer's company, No Prisoners 3DFX, utilizing several of the artists who worked on Wing Commander.  Moyer planned to update some of Galactica's ships, including giving the Vipers the ability to morph into mechanized walkers-à la The Transformers-when on planet surfaces.  Moreover, he and Larson planned to expand the Galactica franchise to include an Imax film, a theme ride, and a new line of merchandise.

Then, as quickly as it had been announced, the project vanished from the radar screen.  It has been suggested that Larson and Moyer ultimately found themselves at odds over significant creative issues.  It has also been suggested that the film rights to Battlestar Galactica were still in some dispute.  In either case, the project disappeared into the ethers."

IIRC, Cylon.org had a page on this at one time, but since they revised their site this one and its copies of the concept drawings they had have disappeared.
