Director Brad Furman follows up The Lincoln Lawyer (also known as the film that provided the jumpstart for Matthew McConaughey to serious cinematic respectability) with what seems like a B-movie diversion for Justin Timberlake and Ben Affleck — each seemingly interested in possibly lowering expectations before their next projects. Here, Timberlake plays a poor college student with a head for gambling who runs headlong into a deadly game of chance against a shady offshore gambling crime boss (Affleck); the FBI is keeping close tabs as well. It doesn’t take 20/20 hindsight to figure out the best bet on this one. Opens wide Oct. 4. (R) Not screened in time for review
