Can't believe i left out The Blues Brothers but now I've thought of it i cant pick one to remove to put it in 

I'll give it a go.  It may change by next weekend but right now I'd say:

1) Casablanca
2) Sunset Boulevard
3) Seven Samurai
4) Almost Famous
5) The Bridge on the River Kwai
6) The Passion of Joan of Arc
7) The Godfather
8) M
9) The Big Lebowski
10) Jaws
11) Young Frankenstein
12) The Great Escape
13) Silence of the Lambs
14) One Flew Over the Cuckoos Nest
15) Singin’ in the Rain
16) Psycho
17) The Exorcist
18) Eternal Sunshine of the Spotless Mind
19) Shawshank Redemption
20) Shaun of the Dead
21) Chinatown
22) Duck Soup
23) Amelie
24) Hero
25) Snatch

I didn't think it would be that difficult, but I soon changed my mind when my first list went past 70!
I'm surprised by some of the titles that didn't make my final 25: no Halloween, no Pan's Labyrinth, no Mario Bava or Peter Jackson films and the only reason The Devils didn't stay in was because it's only available as a bootleg 

So here's my final list, though I'll probably disagree with most of it tomorrow. In alphabetical order (no way I can prioritize them):

1.Bubba Ho-Tep (USA, 2002)
2.Akira (Japan, 1988)
3.Once Upon a Time in the West (Italy, 1968)
4.Blue Velvet (USA, 1986)
5.The Elephant Man (USA, 1980)
6.Cyrano de Bergerac (France, 1990)
7.A Short Film about Love (Poland, 1988)
8.Sweeney Todd: The Demon Barber of Fleet Street (2007)
9.Amadeus (USA, 1984)
10.The Incredibles (USA, 2004)
11.Dark City (Australia, 1998)
12.Edward Scissorhands (USA, 1990)
13.Psycho (USA, 1960)
14.Dial M for Murder (USA, 1954)
15.Dead Ringers (Canada, 1988)
16.Moulin Rouge! (Australia, 2001)
17.The Name of the Rose (Germany, 1986)
18.The Dead Zone (USA, 1983)
19.Les Yeux sans Visage (France, 1960)
20.Deep Red (Italy, 1975)
21.Don't Look Now (UK, 1973)
22.Peeping Tom (UK, 1960)
23.Robocop (USA, 1987)
24.The Adventures of Priscilla, Queen of the Desert (Australia, 1994)
25.Nekromantik (Germany, 1987)

Edited into a semblance of preference though it was mostly random.

1) The Big Lebowski
2) Magnolia
3) Pulp Fiction
4) Hard Candy
5) Unforgiven
6) The Princess Bride
7) American History X
8)The Caine Mutiny
9) The Pride of the Yankees
10) Wait Until Dark
11) Tin Cup
12) The Last Seduction
13) The Birdcage
14) Running Scared
15) Return to Paradise
16) My Cousin Vinny
17) Moonstruck
18) Mind Hunters
19) Million Dollar Baby
20) Four Rooms
21) Flawless
