"Transformers: Dark of the Moon" may or may not be the end of the "Transformers" franchise on the big-screen — I'm betting on "may not," for what it's worth — but it's definitely the end for Sam Witwicky.

Like Michael Bay before him, Shia LaBeouf has long said that he's not likely to return to the "Transformers" series following the third installment, which hits theaters tonight (June 28) at 9:00 PM. And when we caught up with the star at the movie's Moscow premiere last week, he reaffirmed that statement — with a surprising twist.

"I'm done with this acting thing in fifteen years. I'll be going into produce," he joked. "I think that's the future, really."

In seriousness, Shia said that when it comes down to it, he just doesn't see a role for Sam Witwicky in the future of the "Transformers" franchise.

"I just don't think right now there's anywhere to take Sam," he said, though he wasn't ruling out a possible appearance far into the future. "If you'd asked me fifteen years ago if I would be here, I would've said, 'No way.' I don't have a grand plan. There's not this grand scheme. I just fall into movies. I'm blessed in that regard. The movies I've been involved in, it's never been plotted and planned and picked. I was seventeen when I met Michael, and I'm sort of Michael Bay-raised. I've learned a great deal from Michael, as a person, as an actor, as a person on set. And it's not that I don't enjoy working with Michael. I love working with Michael. I would do any movie Michael wants to do. I just don't think there's anywhere to take it with Sam."
