Mine include:
Wonderland (the British film with John Simm, not the Val Kilmer one. Great soundtrack)

Morvern Callar (great book, great film, Samantha Morton is uber-cool in it)

Eternal Sunshine Of The Spotless Mind (great idea, stunning cinematography)

Crocodile Dundee ! & 2 (well, I guess loads of people liked it when it came out, but people laugh at me now when I tell them they are two of my favourite ever films).
