LOL. You just named 5 huge blockbuster movies. That's like telling a basketball fan "Other than coaching two different teams to championships, Phil Jackson hasn't done nothin!!" Not counting stuff like Willow and Labyrinth which didn't set the boxoffice world on fire, but were pretty decent flicks in their own right. Also not counting "Tucker" which was always a story he wanted to tell, and got to tell with Coppola.
You forgot Howard the Duck.
