Good, standard list. Like seeing The Usual Suspects quite high. Not much from the 2000's, someone might need a marathon!

I am old enough to have seen Star Wars when it came out (3 times). The cinema I saw it in is now a Hindu Temple! First film I saw at the pictures was Paper Moon, my mum took me when I was ill one day and I might have been underage. The Magnificent Seven was THE film on tv when I was a kid (with The Great Escape) and James Coburn was my hero.
Hope this puts in context why there aren't more oughties films in my top 100. I am an old bloke so my perspective might be different. I think the 70s was the great decade because Alien Jaws and Star Wars back up the Scorcese/ Lumet/ Pakula masterpieces.
Looking at my list above I have a feeling the film at the bottom might enter my all time list quite soon. It's a moveable feast.
