The text of Mamet's American Buffalo rings true, too. This classic study of crooks undone by their competing ideas of successful business should still have seemed the best play on Broadway. This was not its best production, though: In director Robert Falls's oddly mismatched cast, only Cedric the Entertainer, as pawnbroker and fence Donny Dubrow, conveyed the weight of potential menace that should infuse every minute. He deserved to be challenged by a far-scarier Teach than John Leguizamo's bright, almost perky reading of this extraordinary role provided. Like Haley Joel Osment's clean-cut Bobby, everything in Mamet's dangerous pawnshop suddenly became far too tidy.
