There is only one film that anyone should be allowed to take:
ALIEN.
"In space no-one can hear you scream"
Perfect for those howling winter months down in the Death Star when you get lost for the umpteenth time.
If you were allowed a second...
ALIENS...
for the more light-hearted moments.
If you were allowed a third....
The Thing (colour version feat. Kurt Russell)
A perfectly balanced collection.
