It all started when @tatooinesons, a Star Wars podcast, tweeted about his theory that Boba Fett was actually Luke Skywalker’s mother.
Hamill responded with a tweet that said, “I once suggested it to George [Lucas] as the only way we could top Vader being my father. I envisioned her as a double-agent working clandestinely for the Rebels. SPOILER ALERT: He didn’t like my idea.”
Hamill also revealed that he’s, “always been more than willing to generously share my many, many terrible ideas in the off-chance we might stumble across one that could actually be useful.”
Then there was the time I pitched Boba Fett as Luke's mother. I have always been more than willing to generously share my many, many terrible ideas in the off-chance we might stumble across one that could actually be useful. At the time, I didn't even know Leia was my sister. https://t.co/nurhFZZS01

Back in 2004, Hamill told CHUD, “The audience is expecting the unexpected. I kept thinking that Boba Fett would take off the helmet, shake out her hair, and it’s my mother! You would go, ‘Wow, a double agent!’”
