While responding to fans on Twitter , Hamill revealed he's not fond of the wampa arm amputation scene where Luke Skywalker badly hurts the huge snow beast.Hamill was unaware that Luke would take off the wampa's arm in the film, as he was under the impression Luke would only use his lightsaber to scare off the beast instead and not actually harm it. Hamill believes it was out of character for Luke."When filming the scene I was assured my lightsaber swipe toward camera (creature not on set) would simply singe fur 2 scare him off-Horrified to later see amputation & unnecessary cruelty-Wampa was HUNGRY (not EVIL)-Luke would never do this! #StillAngry2017," Hamill tweeted.One fan pointed out the scene was different in the novel, where Luke uses the force to understand what the wampa actually wanted, in which Hamill responded, "my acting was much better in the book."Will Luke be friendlier in The Last Jedi? Fans will find out soon enough when the latest Star Wars film hits theaters on December 15.For more on The Last Jedi, find out how much the movie might earn in its opening weekend and why it's the longest Star Wars film yet.
