Always a popular event, the 'Stars of the Saga' show is hosted by James Arnold Taylor and features whichever guests from the six live-action Star Wars films are there for the coinciding weekend. During weekend #2, it was Jeremy Bulloch and Warwick Davis.
There's a very funny Stormtrooper pre-show also worth checking out. If you'd like to just skip to the show itself, it starts at 16:00. Enjoy!
