The public has an appetite for anything about imagination - anything that is as far away from reality as is creatively possible.
Steven SpielbergI've got a lot of examples about moments where I thought something would work on film and it didn't work, but I never came to that decision with the film half shot, where I was stuck on a runaway train and couldn't jump off. On those occasions where I have admitted defeat, that this is not going to work, I haven't embarked on that project and made that movie.
