I originally expected a big headed alien. When I first saw him he looked like Ray Milland to me.

In an 83 SW documentary Lucas mentioned that people wouldnt or didnt like the "funny old man" but he claimed that that was what was always planned.

I do think the unmasking robbed Darth Vader of his mystique but if he is doing that redemption story it was pretty much necessary.

I think was a little too old though.

I read somewhere that David Lynch was asked to direct ROTJ and he turned it down?
