Hamill talks Star Wars sequels
The actor played Luke Skywalker in three of the previous six films and, following the announcement that a new trilogy is in the pipeline after creator George Lucas sold his company to Disney in a £2.5 billion deal, he hinted that he could return.
Speaking for himself and co-star Carrie Fisher, Mark told E! News: "We have questions about it. And really, they're not even at the stage where they're able to answer those questions because, as far as I know, is there a story yet?"
The 61-year-old went on: "Until I know more about what they have in mind, I think it's better to let Lucas Film make the announcements."
Following Disney's purchase of the franchise, it was revealed that a seventh movie, with the working title Episode 7, is set for release in 2015.
