While Star Wars actor Mark Hamill made his triumphant return as Luke Skywalker in 2017's Star Wars: The Last Jedi, it wasn't actually the only role he played in the Rian Johnson-directed film.In fact, Hamill also brought to life an alien known as Dobbu Scay, who can briefly be seen in the Canto Bight casino. However, while Hamill was credited as Dobbu in the movie's credits, most fans believed the actor had only voiced the character, but that's not the case.

On Twitter, a fan asked Hamill if he had worn a motion capture suit for his cameo role as Dobbu Scay. "It is commonly (& mistakenly) reported that I only did the voice of Dobbu Scay," the star answered, "but I filmed the scene in a full motion-capture suit w/ a giant-sized medicine ball to make me the same size as BB-8. I didn't expect to be credited, assuming it would be another unbilled easter-egg."

Mark Hamill will soon return in Star Wars: The Rise of Skywalker. However, since Luke died at the end of The Last Jedi, the circumstances surrounding his return remain a mystery.
