Speaking to Entertainment Weekly, Hamill revealed that "Star Wars: Episode VIII" filming in England is preventing him from attending SDCC this year. "It doesn't look like I'm gonna be able to make it this year, because of the shooting schedule here. I don't get back until the third week in July."

Addressing the R-rated animated adaptation directly, Hamill added, "I wanted to go, because that's where they're gonna premiere 'The Killing Joke,' and [Batman voice] Kevin Conroy is gonna be there. I'd love to see it with an audience. But it doesn't look like my schedule's gonna allow it this year. My major obligation right now, obviously, is to 'Episode VIII.'"

Well, at least we know Conroy's making an appearance.

The highly-anticipated animated adaptation stars Conroy as Batman, Hamill as the Joker, Tara Strong as Barbara Gordon and Ray Wise as Commissioner Gordon. Directed by Sam Liu ("Justice League vs. Teen Titans"), the film comes from a script by Eisner Award-winning writer Brian Azzarello. Bruce Timm and Sam Register are executive producers, and Alan Burnett is co-producer.
