My top ten

1. Empire Strikes Back

2. Star Wars

3. Return of the Jedi

4. The Phantom Menace

5. Cutscenes on Dark Forces II: Jedi Knight

6. Cutscenes on Rebel Assault II: The Hidden Empire

7. The episode of Animaniacs that parodies Star Wars, featuring Pinky as C-3PO and The Brain as R2-D2.

(and from this point on we drop down into the realm way below barely watchable,)

8. Star Wars Holiday Special

9. Ewok TV movies

10. Droid and Ewok cartoon episodes edited into features to sell on VHS

...

Oops, that's ten already. No room for episodes 2 and 3, a true shame really... oh well.
