Who would YOU put in a remake?

Just for fun I like to think about who would possibly be good in a remake- not that I think anyone could do any better...this movie already has a perfect cast. But just for fun, who would you choose? I think:

Ray- Jason Bateman
Art- Jack Black
Lt. Rumsfield- Bradley Cooper
Dr. Klopek- Kevin Spacey
the other Klopek- Robert DeNiro
Carol- Jennifer Aniston
Ricky- Justin Bieber ?
Rumsfield's wife- Cameron Diaz
