Alan Bennett’s breezily written but ferociously intelligent and allusive play (unless you know your Auden from your Larkin, you may wish to take along a Comp Lit major) places us in a classroom of lads preparing to take the essay tests that could get them into Oxford or Cambridge. As the day of the test nears, the boys must navigate the competing influences of two radically different instructors. Every groove hasn’t quite been quite worn smooth, and there’s some settling still to occur, but the actors in Studio’s production have found the easy, offhand rapport this play demands. As a result, Joy Zinoman’s staging is smart, funny and touching—in several scenes, it’s all three at once.
