(written as Noises Off)A farce by Michael Frayn, first performed in Londonin 1982. The play is chiefly remarkable for having what has been called"the most difficult single act to perform ever written."The act in question presents a third-rate travelling company's productionof the feeble sex comedy Nothing On. During this farce-within-a-farceeverything that could go wrong does go wrong, as lost contact lenses,missed cues, drunkenness, and backstage squabbles combine to producea terrifying descent into chaos.
