Theatre Camp (out Sep 7) is a light, breezy watch. It's a Christopher Guest-inspired mockumentary centred on a summer camp for nerdish kids who love acting and musical theatre. The idiosyncrasies of the adult characters are overcooked and I wish we saw more focus on the kids (they're great) but there's still plenty of laughs on offer - some quick, throw-away gags and some requiring a longer set up (like the climax to the camp ending musical). Grade: B.
