Hilarity and chaos ensue in Curtain Call Theatre’s production of Michael Frayn’s ingenious play-within-a-play Noises Off, about a third-rate British acting troupe desperately trying to stage and tour a third-rate farce called Nothing On. Noises Off is a hysterical story about a theater troupe’s misadventures. As actors in this play-within-a-play rehearse, forgotten lines, dropped trousers and lost plates of sardines create onstage pandemonium. Meanwhile, it is total chaos backstage as love triangles, petty bickering and ruined affairs lead to pratfalls, flying props and more than one bloody nose. In the end, at the frenetic final performance, everything merges into one perfectly ravaged and wholly uproarious theatrical nervous breakdown.
