Some great choices there :0) Although who said Dirty Dancing? Yeeuuck :0(
Pulp Fiction, Blade Runner and The Blues Brothers are in my top 'few' I guess but to be honest there are few films that make me smile quite like the old ones, like Some Like It Hot, How To Steal A Million and My Fair Lady.
Going to watch Alien tonight, maybe one of the best sci-fi-horrors ever made. And how good is Shaun Of The Dead ? ;0)
