The majority of people are mentioning the Disney classics so I assume we talking about the Disney animation classics, right? I don't know if the Pixar or any a\other 3D animations count, since some are mentioning the 3D films as well.
Disney Animation Classics:
1. Lion King
2. Aladdin
3. Beauty and the Beast
Disney/Pixar 3D animations:
1. Finding Nemo
2. Frozen
3. Monsters Inc.
Disney Live-Action:
1. Pirate of the Caribbean franchise
2. Mighty Joe Young
3. The Count of Monte Cristo
Disney Marvel:
1. The Avengers
2. X-Men: Days of Future Past (I don't know if this one is Disney, I didn't see the Disney logo at the end of the credits unlike Avengers and Iron Man where it is displayed, Although Disney owns Marvel)
3. Iron Man 3
Since Lucas arts is now owned by Disney, I'm not quite sure what category the new Star Wars and Indiana Jones movies will fit in.
