Coraline - Good film, and completely stop-motion. That's right: a stop-motion movie released in 2009. http://www.youtube.com/watch?v=vQC0QVXa33o.
Enchanted - Rips the Disney fairtale apart, plays with it, and puts it back together. Well done, and touching without being annoyingly soppy.
The Princess Bride - An awesome tale of adventure. Here's a quote:
Spoiler Inigo: I admit it; you are better than I am.
Man in Black: Then why are you smiling?
Inigo: Because I know something you don't know.
Man in Black: And what is that?
Inigo: I am not left handed! [switches sword to his right hand & they continue fighting, with Inigo winning]
Man in Black: You're amazing!
Inigo: I ought to be, after twenty years.
Man in Black: There's something I ought to tell you.
Inigo: Tell me.
Man in Black: I'm not left-handed either. [switches his sword to his right hand]
Eastern Promised - Has Viggo Mortensen in it. That's a good enough sign on its own, isn't it?

Another vote for
Tangled - one of the best Disney canon films.
Fighting - Worth a watch. Good fight scenes; they come across more as unchoreographed brawls than movie scenes... which is what they're supposed to be

.
http://www.sintel.org/ - Only a short (15 minutes), and free (monetarily and conceptually), though it would still be worth watching even if it cost you money.
Lock, Stock, and Three Smoking Barrels - A classic British things-go-bad-then-worse movie. Plenty fun.
