Middle Age Hollywood

Jolie, 35, acknowledged she once surprised her 8-year-old son Maddox with her disguise as a male naval officer in "Salt."

He came into the room and reluctantly shook hands with the person he didn't know was his mother.

"And I said, 'Honey, it's mommy,'" Jolie said.

"I think I freaked him out," she said with a laugh, adding that he then watched her peel off her fake ears, hands and nose.

"I play these roles, but I'm always in every minute their mom first," she said. "I'm a bit of a goofy. I'm funny at home, I think."

Her children aren't going to be seeing the movie, though.

"I think it's very hard for them to see someone trying to kill their mom, even if she wins," she said.
