Exactly the kind of film that makes us think Tribeca is maturing, Bradley Rust Gray’s The Exploding Girl derives its title from a Cure B-side (”The Exploding Boy,” to be precise) but otherwise feels very personal. Surface traits peg the movie as mumblecore [Shudder]: Brooklyn locales, the headbound ennui of college-educated twentysomethings, plenty of verbal awkwardness. But Zoe Kazan’s central performance—as a moody epileptic shaking off a breakup—anchors the film with uncommon emotional heft, thoughtfully left unresolved. (Kazan is probably tired of reading about the Hollywood royalty she springs from, so let’s just say we’ve got a rising star on our hands.) The film screens several more times during the fest, including this afternoon. Tickets appear to have moved fast, but there’s always the rush line, a more effective option than you might think. Try. You won’t be disappointed.
