If you think Mark Hamill -- Luke Skywalker himself -- knows everything about Star Wars, think again. When it comes to Star Wars lore, Hamill will defer to the super fans.

In a wide-ranging interview with StarWars.com, Hamill took on some fan questions about Luke's adventures in the original Star Wars films. One such fan happened to be Hamill's own son, Nathan. Nathan Hamill asked why Luke's plan to rescue Han in Return of the Jedi doesn't really add up to make as much sense as it should.

"When you described all that about Return of the Jedi, I just lost you completely," Mark Hamill said. "I forget that plan and I don't remember!"

Hamill went on to discuss how the fans generally know more about Luke, Leia and Han's exploits than he does.

"I’m kind of intrigued now, because people use logic and they’ve seen these movies so often that, like you say, they’ve discovered a flaw in the logic or the feasibility of whatever Luke’s plan was," Mark Hamill said. "You hope it will be a hit. You hope people will go back and see it two, maybe three times, because that’s what makes a movie a super hit. We never expected people to see it 30 times and write dissertations and theses and discuss it in that kind of detail. Like I tell people when I talk in front of large crowds, we called him the 'medical droid.' We didn’t call him 2-1B. They didn’t name him that until he became a toy and they had to copyright the little action figure. So they know the movies better than I do. I hate to disappoint you, but it’s true."
