The film follows Team Meat's Edmund McMillen and Tommy Refenes of Super Meat Boy fame, Phil Fish and his game Fez, as well as Jonathan Blow and his game Braid. It's currently set for a fall release, though filmmakers James Swirsky and Lisanne Pajot -- the minds behind the movie -- are looking for a bit of help to add that last bit of polish.
The Kickstarter page has the details, but to sum it up, they're looking to "get the feature film done right and taken to the next level, technically-speaking." Things like audio, color, and mastering.
It looks like a swell film. Looking forward to seeing it. If you've any interest in it, you may as well support them by pre-ordering or backing their Kickstarter page.
