There's no point in looking back, because there's nothing you can really do to improve the film. You can only aggravate and wish you had done stuff better.
Woody AllenI've never been satisfied or even pleased with a film that I've done. I make them, I'm finished, I've never looked at one after. I don't like them because there's a big gap between what you conceive in your mind when you're writing and you don't have to meet the test of reality. You're home, you write and it's funny and beautiful and romantic and dramatic, and then you have to show up on a cold morning, and you don't have enough of this and this goes wrong and you make the wrong choice on something and you screwed up and you can't go back.
