When I was a child, my favourite movie was The Great Escape. I still think it's a great movie and is in my top ten; however, it has been taken over by a few others now and I don't have a favourite movie as such.
In no particular order:
The Great Escape
Goodfellas
The Usual Suspects
Memento
The Shawshank Redemption
Fight Club
The Empire Strikes Back
Schindlers List
Reservoir Dogs
Donnie Brasco
Here are some of my favourites, although I have a lot more and I can never choose between them
One Flew Over The Cuckoo's Nest
A Clockwork Orange
Fear & Loathing in Las Vegas
American History X
Taxi Driver
Goodfellas
Blow
Good Will Hunting
Rounders
Fight Club
Reservoir Dogs
Almost Famous
Mystic River
The Road Warrior
The Shawshank is up there for me too
Grease was the film I probably enjoyed most at the time 1978/9? I still think it's ok now but I'm not 10 anymore
Used to watch East of Eden a lot when I was younger
A Time to Kill as well
