PLEASE tell me What Happened to you in The Kingdom?!  I have won several bets, by your presence in the first 'conference room' scene, your two lines (possibly 3) and your mysterious disappearance from the film.  My theory was that you were written out due to contract/obligatory conflicts - time overbooked - and they decided tojust leave the scene in to Totally Aggravate and Bewilder simple folk like me - just the 'watchers of films' that don't have a life of their own - living vicariously through HBO. . .
But, I could win the last big bet if I'm right about this:  that your 'part' in the film was simply -somehow- written out, and NOT that they just happened to find you on the set that day, so they thought they'd ask you to Mess with your Fans and just be there like you'd be in the rest of the movie . . . only to have you . . . gone.  Thanks.  Love your work!  Lions for Lambs?  Oh Yeah. . .
