To follow-up on my post a few days ago about the charity screenings of EMPIRE that were held a few weeks ago....it was the 2004 edition screened. The following site states that, "I can report it was a digital copy of the special edition without the Luke scream. If you’re a Star Wars fan…you know what I’m talking about." Celebrate the 30th anniversary of the film by screening the 2004 DVD edition? I'd have griped, especially because of the replaced Fett voice.
