The IMDb has a new blurb about how Lucas is impressed with his latest Anakin:

Hayden Christensen landed the role of Anakin Skywalker/Darth Vader in the Star Wars prequels, because he didn't laugh at George Lucas' bad jokes. The Canadian actor was invited to meet the Star Wars creator at his Skywalker Ranch home in northern California after an initial audition, and he went along even though he felt sure Leonardo DiCaprio or Ryan Phillippe had already landed the role. Christensen recalls, "Everyone was saying the part was going to Leonardo DiCaprio and that they were just doing tests to convince the public that they were actually looking at other people. But they told me that George liked me because I had talked to him on some kind of real level, that I didn't treat him like the Almighty George Lucas. When you get to the level of success George has gotten to, it's hard not to have people laugh at a joke when it's not funny. I wasn't doing that."
