Wow, your movie list is awesome.
I have, like, over a thousand movies, so it's really hard for me to choose favourites.

Interesting Post.
I really want to see Donnie Darko. I love Ferris Bueller's Day Off!
Here is mine (Not in any specific order. Just whatever came into my head):
The Dark Knight
Titanic
Brokeback Mountain
Interview With The Vampire
Wedding Crashers
Old School
Good Will Hunting
The Bourne Identity
Troy

I love movies which is why I created this group so these ten are just a few out of my list of a bunch of my favorite movies. Lol.
-Renegades

That's a really hard to answer!

As reading down the lists I was like "TITANIC!! <3" and "BROKEBACK MOUNTAIN!! <3", so I am guessing those two would be on my top 10.

Looking at these lists made me realise I should rent some more movies from Netflix as I have no seen many of them or maybe I have and just don't know them by name...
