For me, personally, It would be Snatch. It's such a great movie that I could watch again and again. So many interesting characters and a unique style that sets it apart from so many other movies. There's just that extra something in that movie
What about you, fellow Lemmites? What is your favourite movie?
My tastes change from time to time, and even if they didn't it's difficult to choose one across all genre. But I think my all-time favorite is The Princess Bride.
