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?
The Big Lebowski.
I lie to people about how many times I've seen it because I don't want them to think I'm crazy (if you though about a number, it's more than that).
Every line of dialogue is simply a masterpiece.
