The new gambling thriller Runner Runner is due in theaters next month (Oct. 4 to be exact) and a new trailer has arrived online.

Since the release of the last trailer, there’s been quite a bit of movement involving the careers of the film’s two leads, Ben Affleck and Justin Timberlake.

Affleck, of course, was announced as the new Batman a couple weeks ago. Timberlake later followed saying that he would like to play The Riddler.

Watch what happens when Batman and The Riddler meet in the new trailer for Runner Runner!
