OK, I’ve mentioned (below) casting Bush and sKerry as characters in LOTR, and although typecasting like this would seem to be simple, I did have to search a bit to cast one of the players…
Bush as Samwise Gamgee is a pretty solid fit in terms of character, although I doubt Sam ever earned his M.B.A. sKerry as Grimma Wormtongue is a lock: a minor character with undue negative influence on an entire people. Cheney was a little tougher, but only because he just doesn’t fit the physical description of Gandalf. He can be as warm as Gandalf, and as folksy, but if I had a Balrog coming up fast on my six, I’d be glad to hand off to Cheney as Gandalf.
The really tough one to cast, though, was Edwards… I mean, seriously, there was not one single character in the books I could come up with for a role for him, until… hmmm… Yep. It fits. Edwards as the inspiration for the name of the inn where the hobbits met Aragorn: The Prancing Pony.
