I remember telling the 'Tangled' crew about grimace moments: how when you watch a movie that you worked on and you think, 'Ah, I wish we could have done that scene better,' or, 'I wish that we'd had the time or the money to fix that particular story problem.'
I have worked with several art directors and production designers who are just magnificent. Dave Getz, Paul Felix, Ian Gooding... just amazing artists, and I would say, if I had anything to do with it, I just pick good artists!
