All roles have been cast, save for the role of Alec Baldwin's one-scene walk-off steak knife offerer "from downtown...on a mission of mercy." Granted, this role was not in Mamet's original play and crafted specifically for the silver screen but, really, not having Alec Baldwin's role in "Glengarry Glen Ross" going forward would be like watching that one episode of "Seinfeld" where Jerry Stiller wasn't Frank Costanza.
So......who should play this part for Reitman? Well, I considered concocting a Top 5 but that was, of course, unnecessary. The choice is clear. I expect it to be made soon (now).
