I'm a newbie here and posted this question on a separate forum (knowing that it must have been covered already).

My vote for Harry?  Vince Vaughn.  He's got the height, the sarcasm and the acting skills.  He hasn't always done comedies like "Wedding Crashers".  The first movie I remember him in was "Return to Paradise" with Joaquin Phoenix and that was a pretty heavy drama.  I think he'd be perfect.
