Trivia: Luke Skywalker actor Mark Hamill stated in some interviews that wasn't sure about the film's treatment of his character at the start of production, but he still stuck with the script out of respect for director Rian Johnson's vision. When news of this was revealed, many misconstrued his comments and concluded that Hamill disliked the film. On the contrary, Hamill later clarified that despite his initial hesitance, he thought the finished film was quite good and a worthy addition to the series.
Trivia: When Kylo swings his light sabre towards Luke during their fight on Crait, the "Wilhelm Scream" can be heard.
Trivia: The name of the bird creatures on Luke's island ("Porgs") is never mentioned in the film. Much like the Ewoks in Return of the Jedi.
