All-time favorite and has been for 15 years...Casablanca. Couldn't tell you how many times I've watched it. Perfect cast, perfect script, perfect cinematography, perfect lighting, perfect set....when Sam begins playing "As Time Goes By" by Ilsa's request, the camera hovers on her and captures one of the most beautiful 5 seconds in film, in my opinion. So beautiful and so sad in that microsecond and you are right there in the room...you want to be at Rick's Cafe American...*whine*
The rest of my list: Citizen Kane, Godfather 1 and 2 (Godfather 3 can rot in hell), One Flew Over the Cuckoo's Nest, Highlander, All About Eve, Big Sleep, Ocean's Eleven (Clooney/Pitt remake), Robin Hood (Disney), LOTR trilogy, Star Wars and Empire (original, not that blasted "touch-up"), Streetcar Named Desire, Sunset Blvd, Die Hard, Rocky, Alien, Aliens, Elizabeth, Pushing Tin, Life Aquatic, Princess Bride, Princess Diaries, White Christmas, Sahara, Doctor Zhivago, Lawrence of Arabia, Bridge over the River Kwai, Roman Holiday, Breakfast at Tiffanies...
