Napoleon Dynamite star Jon Heder is to star in the science fiction film, Buddy Holly Is Alive and Well on Ganymede. The actor, who had a huge hit opposite Will Ferrell in Blades of Glory, has also signed on to headline an untitled sitcom, and will shoot the quirky sounding science fiction film when that goes into hiatus. With the exception of 'Glory', Heder hasn't really hit his stride since breaking onto the scene after 'Dynamite' was a surprise sleeper hit a few years back. I can't see him really shining in a "live audience" type comedy, but a single camera laffer such as Scrubs would suit him down to the ground.
