It depends how much...
  1. I'd invest in a diverse portfolio...
  2. Buy a house in New England, somewhere. For writing.
  3. Pick up a DeLorean.
  4. I'd buy a decent place in L.A.
  5. I'd finance a few indie feature films... Ideally something for Terry Gilliam. Man of La Mancha anyone?
  6. I'd also produce my own directorial debut.
  7. And I'd take this beautiful girl I know on a date, anywhere in the world she wanted to go.
