Agree with a lot of your choices, Back to the Future must be the overall winner and I wouldn't disagree with that. Top of my list and it hasn't been mentioned would have to be Amadeus have the directors cut on dvd and only watch it every year or so but could watch it every week. North by Northwest The Carry on Films Ealing comedies Close Encounters Enter the Dragon Goldfinger Matrix
The Bishops Wife (the orginal)
A Matter of Life and Death
Goodbye Mr Chips (again the orginal)
Dirty Dancing
Coyote Ugly
Heartbreak Ridge
A Few Good Men
Stepmom. I know some people might find it a little corny but I just love that film! I could quite happily watch it over and over again, very underrated.
The ending always leaves me in tears!
