Will Smith has played his share of famous men in film, but is he ready to play a (possible) president of the United States?

Senator Barack Obama has singled the man in black out as his choice to portray him in a biopic on his life, if only because they share one conspicuous physical attribute.

"Will and I have talked about this because he has the ears!" he tells Entertainment Tonight.

Although you may never know it from the intense campaigns and debates, the presidential hopeful is quite the film buff, naming The Godfather Part 1 and Part 2 and Lawrence of Arabia as his favorite flicks.

"I love Jimmy Stewart, Spencer Tracy, Humphrey Bogart, Meryl Streep, Susan Sarandon and Angela Bassett," he says.

These days, the 46-year-old doesn't have much time for movie night or much else, lamenting the lack of writing and reading he has done since his campaign has commenced. The lifestyle is quite difficult on his health too, but he tries his best to keep it in check.

"I try to have three square meals. Sometimes when you're out in remote areas there's not much you can do," he says. "You go for a burger, that's safe. If you start getting fancy you could get into trouble. If you're in a place like Iowa or Wisconsin there's gonna be cheese on just about everything. If you start eating too much junk you'll never survive."

As for his family, wife Michelle and daughters Malia, 9, and Natasha, 6, they are the backbone of his support — even if some of it is the result of bribery.

"The deal breaker is getting [my daughters] a dog," he reveals. Their whole thing is after the campaign, win or lose, they will get a dog. Sometimes I worry they're rooting for me to lose so they can get their dog quicker."
