Billy Dee has passionately argued that Lando is not a traitor. It even became a robot chicken sketch. ;)

I've also realized we probably got stiffed on a lot of deleted ROTJ footage on the Blu Ray, as none of the alternate takes of the Endor forest battle footage used in the second Ewok movie are present.

I suspect the Ewoks got softened up in the editing process. There's a quick cut in the movie of one waving a stormtrooper blaster, but you never see them firing it. Only George knows what's still in the vault.
