It will be interesting to see whether this big-screen adaptation of a literary classic will be great (eg LORD OF THE RINGS) or disappointing (too many to name). Crime fiction fans worldwide will be holding their breath. And no doubt arguing about it after the fact.
And now, reports are coming out that an even bigger star has joined the cast, with Brad Pitt, another Oscar-nominated actor, being brought in to play Holmes' nemesis Moriarty (who apparently didn't even appear in earlier versions of the screenplay).
