"I think that there were more reasons than that: for one, actors are the single biggest block in the Academy and for all of its merits, the acting in Star Wars ranges from adequate to lamentable." I've got a BFA in Acting from the University of Texas at Austin. Many films have a range of quality of acting, it is almost unavoidable. Personally, I think Harrison Ford, Anthony Daniels, James Earl Jones, Peter Cushing, and even Mark Hamill did some fine work. Hamill was acting what was on the page -- whiny emotional brat. Yeah, he pushes it on occasion, but then, that's sort of the character of Luke Skywalker in Star Wars -- all heart, no head. He learns to find that "zen" through the course of the movie. He is still a hothead in Empire - the plot depends on it - but by Jedi, he has grown up. The only truly ripe performance in Star Wars for me was given by Carrie Fisher, with her faux-British accent appearing when she is in the presence of Peter Cushing, gone when she's hanging out with Harrison and Mark. Still, she has spunk and character to spare, something you can't say of Natalie Portman in the prequels so far, and she's fantastic in Empire (but then, everyone is fantastic in Empire).
