Black Box (2015) is about a box that can grant anyone who finds it what they desire most in the world. Though it bends reality temporarily—only letting users spend small spans of time doing what they most desire—it has permanent consquences: Those who use it are relentlessly chased by an immortal assassin bent on payback. The premise is familiar: What you're given must proportionately be taken away. Luckily, Jason London takes off his clothes and shows us his bare chest as he bones his girlfriends and learns how to swim. Maybe this movie should be called Black Briefs, eh?
