Churchill's subtle, interesting, and creepy play has its full complexity partly trammeled, unfortunately, by ACT's mostly bland production. While things get better over the course of the hour, the opening moments set what feels like the wrong tone. Director Anna D. Shapiro, of Chicago's legendary Steppenwolf Theatre, takes things at a brisk pace, with her otherwise highly capable actors playing the dialogue too much as if it were David Mamet's stylized vernacular (which here tends to encourage playing the lines for laughs) instead of a clinical grafting of language more in tune with the play's fraught tensions, tugging at one another as if in the throes of meiosis.
