This past weekend at DragonCon in Atlanta Georgia. Micheal Hogan went on stage to announce something big. If Universal sells 300,000 copies of The Plan they will produce another BSG movie. This was due to Edward James Olmos they said if the number is reached they will continue to make BSG movies. So go out and tell your friends and family who love BSG to pick this movie up if they want more BSG.
Yes this is a seperate movie that has not been aired yet or shown on TV its going to be released shortly after its aired I believe. There are no plans to add it to any current box sets. That is why Michael Hogan said go out and buy the DVDs. They want to make more Battlestar and its up to the fans to show Universal we want more.
Yes this is separate. Also you should get Battlestar Galactica: Season 4.5 regardless - the extended episode of Islanded in a Stream of Stars alone is totally worth buying the season! It is an entirely different show from the aired version and will change the way you view the ending of the series and likely the entire show. Also The Plan (apparently) deals with the beginning of the series from the cylon perspective so even if you have not completed watching season 4 this is something completely different.
That's the impression I was given with the various auctions of customs, props, set dressing, etc. To further this, on the Commentary Track for "The Plan" EJO & writer/executive producer Jane Espenson note that the original idea was for *3* "stand-alone" BSG movies, but that it was cut down to just one which made "The Plan" all the more important in terms of tying up loose ends.
I personally believe it's due to the fact that after the Miniseries, 4 Seasons, "Razor" and "The Plan" the cast were most likely "straining at the bit" to do other projects and work in other creative outlets (you can pretty much tell in her promo videos that Katee Sackhoff appeared less interested in Season 4), and between that and the costs to keep the sets standing or at least disassembled and put into storage while not knowing if the Producers would be able to get the cast back together from other projects they'd likely be working on were costs they were not willing to take on. Not only the cast but co-Creators/Executive Producers RDM and David Eich have moved onto other writing and Producing jobs, leaving the idea of more Cable movies very much a stretch IMO.
