I'd have to say (not necessarily in order):
Toy Story 1 & 2 (sheer brilliance)
Adventures of Priscilla, Queen of the Desert (very campy but heartwarming)
Everyone Says I Love You (star-studded, musical fun)
Trick (romance is in the air)
Rattle & Hum / BeeGees One Night Only (need I say more?)
Billy's Hollywood Screen Kiss (is he or is he not?)
My Best Friend's Wedding (just for the heck of it)
Austin Powers : International Man of Mystery (pure silliness)
Four Weddings & A Funeral (full of nice quotes, funny lines)
Jurassic Park (never ceases to amaze me)
Sleepy Hollow (well, it is TIM BURTON)
The Matrix (do I really have to justify this?)
South Park : Bigger, Longer & Uncut (you can do it, it's all up to mmmkay !!)
