Foxx is certainly the "man of the moment." While I am not his #1 fan, I think casting him in the D-girls film would be inspired. As many have mentioned, I could see him as either Curtis or Jimmy, but I would prefer he do Curtis. He def. adds star-wattage and is a credible singer.
Laughter is much more important than applause. Applause is almost a duty. Laughter is a reward.
