He told Absolute Radio: "'Star Wars' was really the only sci-fi sort of fascination I had as a youngster. I collected and I've still got the AT-AT and the Millennium Falcon and the Ewok village.
"I suppose they are worth a bit of money. I sort of passed them on I think, and also I took them out of their box."
Describing the Ewok Village, a model of the living area inhabited by the furry alien race, Michael added: "It's kind of like three trees, or four perhaps, they're sort of joined together with the platform bit.
"It's quite cool, you can go into the trunk of one and come out the other, and there's a little sort of wind up trap net thing where you can sort of reel somebody up."
Michael also talked about how he had to "dismiss" other people's opinions when he made 'X-Men: First Class', in which he starred as human mutant Magneto, so he didn't feel the pressure of the avid fans of the Marvel comics.
He added: "There's always a pressure. I sort of had that with 'X-Men' anyway. You know you've got a very large vocal passionate fan base, and you want to do them proud.
"But you take that on board and then you kind of have to dismiss it. Because you want to make choices that are bold and definite, and if you're worried about what other people are going to think other than your director, then the character will be neither here nor there."
