Samuel L. Jackson has not been shy about his desire to return to the Star Wars universe. Late last year, the actor, who played the Jedi Mace Windu in all three of the prequel films, said in an interview that he was so interested in returning to the sci-fi series that he was even up for just playing a one-armed ghost . Now, however, he's not only campaigning for a role for himself, but also for both Ewan McGregor and Mark Hamill. As you can see in the video below, Jackson recently appeared on the Late Show With David Letterman (via Jedi News ), and when the subject of Star Wars came up he revealed that neither actor has heard anything as of yet from Episode VII director J.J. Abrams.While I can understand Abrams not reaching out to McGregor to reprise his role as the young Obi-Wan Kenobi ( despite rumors ), the idea of the filmmaker not approaching Hamill about the project is a serious head-scratcher. While Disney and Lucasfilm have made nothing official in terms of casting since Episode VII was announced last year, fans everywhere have spent the time since basically assuming that the next chapter in the Star Wars saga would continue the story of Luke Skywalker. If Hamill hasn't been contacted by Abrams at this stage, does that mean there's no Luke?We do have to wonder if Jackson is a reliable source in this matter. The reality is that with no real connection to the film he doesn't really have any reason to lie about anything - unless he's been set up to create a smokescreen that will confuse fans and help keep all of Abrams' ideas secret. What do you think?
