Sacramento Theatre Company opens its season with laughter from the rafters to the floorboards in this farce about farces. The second act fairly screams, although the action is almost entirely pantomimed. Michael Stevenson directs at a maniac’s pace, and he’s got a full-on manic cast. Noises Off is a delightfully rib-tickling way to kick-off STC’s season. W 6:30pm; Th 12:30pm, 8pm; F 8pm; Sa 2pm, 8pm; Su 2pm. Through 11/1. $15-$38.
