1. Mulholland Drive
2. Montana
3. Limbs
I'll be fairly impressed if anybody gets this one. The clues are fairly obscure.
Sunset Boulevard.
Nope. I'll give a hint: the first two clues don't have anything to do with the actual plot of the movie, the third one does.
The Big Lebowski?
?
Nope. The movie is from 1993.
Clue #1 relates in some way to the director.
Clue #2 in some way related to the title.
Clue #3 in some way relates to the plot.
