Mark Hamill is best known for being the voice of the Joker in various Batman animated TV shows. But long before that, he played another role, that of Luke Skywalker in Star Wars. What if the two Mark Hamills met?

Youtuber Parry Hotter has created this brilliant fan-edit of the Emperor-Luke scenes in Return of the Jedi, with the Emperor's dialogue replaced with Hamill's voicework as the Joker. It works amazingly well, and changes the whole dynamic of the scene. [via Giant Freakin Robot]
