To this day, Mark Hamill still finds one of the opening scenes in 1980’s The Empire Strikes Back to be unpleasant and upsetting.

Responding to a fan question on Twitter this week, Hamill revealed that he’s not a fan of the scene where his character Luke Skywalker amputates the arm of an attacking wampa creature.

According to Hamill, he was unaware that Luke would be lopping off the wampa’s arm in the film, as he was under the impression that Luke would only use his lightsaber to scare off the beast and not actually harm it. He says he feels the act was out of character for Luke.

One fan replied to Hamill’s tweet by pointing out that the scene plays out in the novelization of the movie, as Luke uses the Force to understand what the wampa actually wanted, to which Hamill humorously responded, “my acting was much better in the book.”

Will Luke still be into his wampa arm-cutting ways when we see him again in The Last Jedi? Or will Hamill have pushed for a friendlier — albeit crankier, based on scenes from the film’s trailers — version of the Jedi Master? We’ll find out soon enough when the next Star Wars film hits theaters on December 15.
