'The Comedy of Errors,' a silly piece played to the hilt
At its heart, The Comedy of Errors is a ridiculous play with a preposterous premise. Scholars will point out its classical roots - two works by Plautus, conjoined - or its early window onto the playwright's later inquiries into identity and power. But this Pennsylvania Shakespeare Festival production, directed at the fest for the second time by Russell Treyz (the first was in 1997), aims straight for the groundlings.
