At its most chaotic, Irishtown brings to mind Noises Off, that classic farce about staging a play within a play in the British hinterland. Comedy, as they say, is hard; and it takes tremendous discipline and timing to pull it off. Under the tight direction of Nicola Murphy Dubey the company mostly meets the challenge though the humor occasionally seems forced. Still it’s quite a trip watching talented actors frantically portraying desperate actors acting badly.
