William Inge’s 1953 examination of a poor but preternaturally priapal young rebel and his effect on the frustrated women of a small Kansas town ends more optimistically than Tennessee Williams’s play on a similar theme, Sweet Bird of Youth. Under the reserved direction of Kevin Theis, the actors in this open-air Oak Park Festival Theatre production lend depth to personalities nowadays reduced to shallow stereotypes–the beauty, the brain, the spinster schoolteacher–amplifying their very human vulnerability. Contemplative audience members will go home with some striking insights into the gender dynamics of the period. Everyone else will be rewarded with a sweetly sudsy romance for a balmy summer night. Through 8/19: Tue-Fri 8 PM, Oak Park Festival Theatre, Austin Gardens, Forest and Lake, Oak Park, 708-445-4440, $17-$25.
