How do you celebrate 40 years of “Star Wars” in 90 minutes?

With a surprise Harrison Ford appearance, a touching Carrie Fisher tribute, a John Williams performance and a fair amount of jokes about George Lucas’s dialogue, of course.

Attendees at Star Wars Celebration were treated to that and more Thursday in Orlando, Florida, at the kickoff of the four-day fan event marking the anniversary of Lucas’ space saga.

A jam-packed panel also featured appearances by Lucasfilm chief Kathleen Kennedy, Mark Hamill, Billy Dee Williams, Anthony Daniels, Peter Mayhew and Hayden Christensen.
