If I could only take 10 movies with me on a 5 year mission through space:
Sunshine
The Fellowship of the Ring
Star Wars
The Princess Bride
The Adventures of Robin Hood
Indiana Jones and the Last Crusade
Dark City
The Matrix
Monty Python and the Holy Grail
The Iron Giant
I debated about having both Dark City and The Matrix in a single top ten list, but I think it’s remarkable how similar concepts can yield such vastly different films. They both stay for now.
