Not bad, he looks enough like him to get the idea across and he is a fun actor who could have given the role the necessary coldness.

Nobody seems to care that Ewan doesn't look or even sound exactly like a younger Sir Alec.

If they were serious about putting Tarkin in the prequels they should of written a role for him and hired someone like Nighy who could have played him without OTT make-up.

I actually thought he was nailing Alec. Ewan's performance in all the movies is honestly why I continued through the entire trilogy. Which brings me to another point... What an amazing cast. I mean really. That was one thing that wasn't lacking... However, if this had been the first time I had seen some of these people act, I would have thought they were horrible actors. Was George that horrible of a director. I don't want to hear "It's because they had to act to green screen." Sky Captain while not perfect, still had great acting despite the fact that it was almost entirely CGI... So, what was his problem here?
