If you’ve seen his car or his flamethrower, you know that Evan Glodell is pretty good at turning hunks of metal into roaring, fire-breathing machines. The same is true of Bellflower, the apocalyptic mumblecore buddy / desert-romance movie he directed, wrote and stars in with the help of a bunch of close friends and a few thousand dollars. Sure, it’s a big mess, but that’s what some of the most ambitious do-it-yourself contraptions tend to look like when they’re done, with seams exposed and a few missing pieces. And yet Bellflower tends to look like, well, nothing else you’ve seen.
