2. Ewan McGregor as Obi-Wan Kenobi
Although there are many of us who have some serious issues with the prequels, you don't hear much smack talk about Ewan McGregor as Obi-Wan Kenobi. Alec Guinness' role in the original trilogy is one of the most memorable in the entire franchise, and yet Ewan McGregor managed to do incredible justice to the part. This is despite the fact that the dialogue in the prequels is occasionally, well, awful.
