Mark Hamill came up with a seriously dark backstory to explain why Luke Skywalker is a reserved loner in Star Wars: The Last Jedi.

"I thought, what could make someone give up a devotion to what is basically a religious entity, to give up being a Jedi. Well, the love of a woman," Hamill explained on the Bullseye with Jesse Thorn podcast. "So he falls in love with a woman. He gives up being a Jedi. They have a child together. At some point the child, as a toddler, picks up an unattended lightsaber, pushes the button and is killed instantly. The wife is so full of grief, she kills herself.”
