The first official trailer was released Wednesday, giving a glimpse at the fast-paced action thriller that's based on real events.
In it, Affleck plays a wealthy businessman, thanks to his successful (and less-than-legal) online poker companies. Timberlake takes on the role of a Princeton student who takes a bite out of the competitive online gambling world.
After learning that Affleck is more enemy than friend, and that he's in serious trouble with the law, JT is left fighting for what's left of his fortune.
The two battle it out in what appears to be the movie to see this fall.
The flick also stars Anthony Mackie and Gemma Arterton. Runner, Runner hits theaters Sept. 27.
And while Affleck is taking his turn at playing the bad guy, it's only a matter of time before he's donning a batsuit for his role as Batman. It was announced last month that the hunky Hollywood actor would be taking on the coveted character for the Man of Steel sequel alongside Henry Cavill's portrayal of Superman.
During an interview on Fresh 102.7's Jim and Kim Show Timberlake spoke out in support of his Runner costar's ability to take on the bat role, despite tons of casting criticism.
"I worked with Ben last summer and I've seen his process. I think he's a brilliant filmmaker. I think he's an extreme talent, so he could surprise a lot of people."
But when Justin was asked if he'd want to play Robin, he answered with a laugh, "Not a chance in hell," clarifying, "I ain't playin' Robin. I have no aspiration to ever be a superhero in a movie. Now villain? I'll tell you the villain I want to play more than anything because I grew up loving Batman, funny enough, is the Riddler. The Riddler is my favorite villain."
"The Riddler was like a sociopath," he added. "He was proper crazy. So if I'm gonna play crazy, I'm wanna play proper crazy."
"I'm ready," he said. "The Riddler. Gimme a call."
Now that would be awesome!
