One of Star Wars’ best pilots won’t be returning in Episode VII. Denis Lawson, who played Rebel ace Wedge Antilles in the original trilogy, has confirmed that he turned down the chance to return in the upcoming Star Wars sequel. Speaking at a screening of his new movie, The Machine, Lawson said “they asked me but it just would have bored me.”
Wedge — not to be confused with the Captain Antilles strangled by Darth Vader minutes into Episode IV — appeared as a hotshot pilot in all three original movies. While his part was minor, Wedge notably helped save Luke Skywalker during his attack on the first Death Star, survived the battle of Hoth, and contributed to the destruction of the second by flying into its core alongside Lando Calrissian. According to Badass Digest, Lawson suggested he might have returned if the role was increased in scope, but ultimately rejected the offer.
