Great list spyware. I like a lot of those movies on your list. 
I've always been a fan of the Mafioso movies and any Bruce Lee films. 
Godfather I, II, III - Every time I watch them I pick up something new. I've probably seen each of them at least 50 times.
Heat - One of the most underrated classics of all time.
Casino - Great movie and outstanding cast.
The Last Samuri - I liked the message of the movie, Tom Cruise should've died though
Star Wars Trilogy - Yoda, Ewoks, Darth Vadar, Han Solo great stuff
Juice - 2Pac's best movie starring as Bishop,

Bishop: You know what? Last time you said that, I was kinda trippin', right? But now, you're right. I am crazy. And you know what else? I don't give a ****. I don't give a **** about you. I don't give a **** about Steel. I don't give a ****** about Raheem, either. I don't give a **** about myself. Look, I ain't ****. And you less of a man than me, so as soon as I figure you ain't gon be ****, *pow*! So be it. You remember that, ************. 'Cause I'm the one you need to be looking out for... *partner*! </div>
I love that line from the movie.
