Haley Joel Osment Explains His Dramatic New Movie Look

Last week, the former child star emerged looking very different.

— -- Last week, former child star Haley Joel Osment raised a few eyebrows by walking around Los Angeles looking -- different.

Now he's explaining the details of the film project, "Yoga Hosers," that he was working on at the time.

"I play a real person -- a comic version of a real person named Adrien Arcand, who was the Canadian fuhrer in the '30s and who thought he could bring about the Third Reich in Canada, too," Osment said on "Access Hollywood." "All last week I was standing on a crate in downtown Los Angeles screaming Nazi things, which, oddly, the Internet took notice of."

"It's not a popular look, the [Nazi] armband and everything," he added, "but there was a reason for wearing it."

Osment, 26, rose to fame years ago with roles in "The Sixth Sense" and "Forrest Gump." Now, not only is he shooting "Yoga Hosers," but he also just wrapped a film called "Walrus" alongside Justin Long, and the "Entourage" film.

"I had such a blast on that movie," he said. "I really think, too, that it's a movie that's gonna be the perfect thing that everybody who loved the show wanted."
