Our JANN CARL goes in-depth with presidential hopeful BARACK OBAMA as he reveals who he thinks should play him on the big screen as well as admitting what his wife is allowed to do -- that he isn't!

"She is very funny, she can really make you laugh," Barack says of MICHELLE. "Sometimes it's at my expense. She's allowed to tease me, but I'm not allowed to tease her. That's sort of a rule of our marriage that I've abided by."

The Illinois senator also talks to Jann about all things Hollywood, including who he'd like to play him in a movie. "WILL SMITH and I have talked about this, because he has the ears," Barack says. "He's better looking than me, but we both have those."

Speaking of stars, Barack rattles off a few of his faves. "I love JIMMY STEWART, SPENCER TRACY, HUMPHREY BOGART, MERYL STREEP, SUSAN SARANDON and ANGELA BASSETT," he says.
