What is this Luke's saber color change deal?
If it's the Falcon shot, then I think that is some type of grafics corruption going on.
Something, like with the badges in RotJ being all wrong, is of a technical natur and should just be ignored.
As for Greedo still
shooting first, I can hold my peace about, as they have speeded that scene up so it appears more that Han shoots almost at the same time as Greedo, while ducking away at the same time. It's over so fast you can barely notice the cheesy headbob (photoshop job
) done by Han.
The whole Jabba scene in ANH looks cheesy to me, with the original actor, and with Jabba.
