Who's Who: Casting 'Election 2008: The Movie'

Finn: There's this actress named Sanaa Lathan, she's stunning, smart, composed. She'd be a perfect glamorous, elegant Michelle. But also, the stage actress Audra McDonald could be a perfect regal, forthright, fearless Michelle.

Joe Biden

Sam Shepherd and James Cromwell could be candidates to play Biden.

Finn: Sam Shepherd. Biden's got this very verbal, articulate thing going on, and Sam can do that effortlessly.

Bowen: Harrison Ford as Joe Biden, next to Will Smith as Obama, wouldn't that be great? He can embody that career politician persona.

Wilbekin: James Cromwell. He played George Bush Sr. in "W." I think he's very smart, very calming, and I think he could walk the line of being this great orator while running away at the mouth. He's got the poise that Biden has, he's got the look and he's also warm.

Sarah Palin

Could Julia Roberts play Sarah Palin as well as Tina Fey did?

Finn: Let's face it, Tina Fey would be hard to beat. But if you want a more straight-laced Palin, I can see Reese Witherspoon pulling it off. She's got that spunk. But also, a dark-haired Nicole Kidman circa "To Die For." She's be a strong Palin.

Kaufman: Julia Roberts. You could make her look like Palin -- there's that big, smiley thing about them. Palin's so homey, she's almost Southern. Julia can really carry that. And Tina Fey really nailed it. We'd all go see that movie if Tina was Palin. If neither of those names were available, I'd pick Catherine Keener.

Wilbekin: I mean come on, Tina Fey. No one else need play her. She's perfect. From the mannerisms to the physicality. ... Tina Fey did a great job of capturing all of her idiosyncrasies and also all of her moose-shooting weirdness.

Bowen: Tina Fey, there's no one else who could play Sarah Palin. Just no one else.

John McCain

Robert Duvall has the experience to play John McCain.

Bowen: Ed Harris -- he's played general and military guys before. He has an austereness that McCain has. I'm sure he can be made to look older.

Wilbekin: Ed Harris is charming, he's intense, he's smart, but he kind of has this very hard edge to him. He has a certain endearing quality that we saw in McCain the night of his concession speech. Ed Harris can walk that line of being very strong and gracious at the same time.
