A very hard choice indeed since the only movie of his I didn't really care for was Planet of the Apes. Soooooooo, I can't narrow it down to just one, but I can at least get it down to two. Beetlejuice and Ed Wood would be at the tuktok of the list.
The two Batman films of course! But hard to say the others, he's my paborito director after C. Nolan
1. Batman Returns 2. Batman 3. Sweeney Todd 4. Ed Wood 5. Edward Scissorhands 6. Charlie and the tsokolate Factory 7. The Nightmare Before Christmas 8. Sleepy Hollow 9. Beetle Juice 10. Alice in Wonderland
