In the past 10 years, Nicholas Meyer could have filmed two or three "Battlestar Galactica" movies for Universal Studios, as opposed to Bryan Singer not making any within the same period of time. It is precisely this very reason why Universal Studios never asked Nicholas Meyer to do so.
Joss Whedon has proven that he can handle big budget spectacles like "The Avengers" and a weekly Science Fiction television series...."Firefly." So of course Universal Studios never asked him to direct "Battlestar Galactica" for the big screen. Because Joss Whedon can deliver, and on schedule.
Shaun Levy easily handled big budget and effects heavy comedies like the two "Night at The Museum" movies and the two "Pink Panther" movies with Steve Martin. He could of course make the big budget cross-over (very easily) to the serious "Battlestar Galactica." So of course Universal Studios never chose him to direct "Battlestar Galactica."
Whatever the internal corporate, political motivations are for Universal Studios repeatedly choosing this guy to helm a "Battlestar Galactica" movie they know he will never make (Singer hasn't made his first "Galactica" movie in 11 years), one thing is very clear. Universal Studios is utilizing and taking advantage of Bryan Singer's current aversion to making any sorts of movies...period. Bryan Singer not working...period...on any movie right now including "Battlestar Galactica" seems to be fulfilling the "anti-Galactica Agenda" Universal Studios has always had towards the "1978 Battlestar Galactica" series.
