Who would be a good actor to play Mitch from A Streetcar Named Desire?

I'm doing this school project and we have to create our own cast for A Streetcar Named Desire by Tennessee Williams. I have all the other characters casted (like, I have Reese Witherspoon as Blanche), but I'm having issues thinking of someone to play Mitch. Anyone who has read or knows the play, can you throw out some ideas of a good male actor to fit the part? It would really help alot!!! Thanks!
