Miller: It’s extremely painful. Every day I wake up and- (LAUGHS). Y’know, the directing part is not that different and I think running a bigger company had a lot of value to running a bigger- I mean this-basically this production is about the size of business my company does in a year sort of crammed into a six month period.

The Brew notes how the movie was a looong time in gestation, and that Fox wasn't gung ho to make it until these footage leaked out and momentum began to build.
