We had the joy at Star Wars Celebration Anaheim of sitting down to chat with Dickey Beer, who is credited with some of Boba Fett's stunts in Return of the Jedi.
Learn more about his experience as multiple stunt doubles and the real challenge of falling into the Sarlacc pit. (Other Boba Fett stunts in Jedi were done by Glenn Randall Jr. and Bob Yerkes.)
