"Fans will get an exclusive first look at some of the collection's extensive special features at this year's San Diego Comic-Con International -- which marks Lucasfilm's 35th anniversary as a Comic-Con presence. In 1976, the fledgling film company was looking for innovative, grass-roots ways to promote its underdog release, a film no one expected to succeed -- a space opera known (at the time) only as Star Wars. One of the first film companies to reach out directly to core audiences by way of fan conventions, Lucasfilm will return to the venue to showcase the full evolution of the epic story with a special first look at STAR WARS: THE COMPLETE SAGA ON BLU-RAY.
