There's definitely a luxury to the fluidity of not being a mega-star. I've done a ton of really, really odd, off-the-wall movies. There's this movie I did called 'Queens of Country' a couple of summers ago that is so bananas, and if I was at a certain level, I probably would not have done that movie
Although this is a fictitious story the history is real. You don't want to re-write history but you certainly want to portray events and characters as realistically as you can.
