Worst possible casting choices

[Boromir88]

And do non Brits have a clue as to who most of them are?

Well of course I know who the Governator is, who can not know him?

And Roy Kinnear was Planchet in several Musketeer movies...don't know exactly which ones there are so many of them and all these spinoffs.

Everyone else I really have no clue, but the Aragorn guy looks familiar...so far can't pin him down.
