With the exception of maybe those living in Gotham City, the world discovered last week that Ben Affleck is the new Batman.

But before he slips into the Batcave, Affleck has a different role to play. In fact, next time Affleck hits movie theaters, he will be the villain.

Affleck, Justin Timberlake and Gemma Arterton star in Runner Runner, which is scheduled to hit theaters nationwide Oct. 4.

In the film, Timberlake plays Richie Furst, a Princeton grad student and avid online gambler. When Richie gets cheated out of money and loses his tuition chips, he travels to Costa Rica to challenge his swindler. Ivan Block (Affleck) meets him on the other end.

Rather than show anger, Richie is intrigued by Ivan's estate. Through his immoral actions, Ivan creates an elaborate lifestyle for himself in the Caribbean. Ivan sees a useful mind in Richie and reciprocates by taking Richie under his wing. Richie falls for Ivan's COO, Rebecca Shafran (Arterton) and things seem to be working in life.

The Island Party takes a turn when FBI Special Agent Shavers (Anthony Mackie) closes in on the group. Ivan is a wanted man, and once he begins working with Ivan, so is Richie. Richie must do all he can to stay out of prison, although it appears his luck has run out.

Runner Runner will not be the first time Timberlake plays a young genius trying to get-rich-quick. In The Social Network, he played Napster founder and founding president of Facebook, Sean Parker.

"The American dream used to be about being rich and famous, but now it's to become rich and famous – as quickly as possible," Timberlake says. "The more access we have to things, the faster we want them. Just touch a button and you can have almost anything shipped to you."

As Runner Runner displays, rushing to the finish line can be dangerous in the world of business. Young people will do anything for money. In the film's case, young people will oversee illegalities for wealth.

"[Ivan] holds up that wealth, which blinds Richie to what's really going on," Affleck says.

Screenwriters Brian Koppelman and David Levien are far from novices in the gambling-writing field. They also wrote Rounders and Ocean's Thirteen. Other titles the duo has written include Solitary Man, The Illusionist, Runaway Jury, The Girlfriend Experience and Knockaround Guys. Levien is also a novelist and Koppelman a regular Grantland contributor.

Runner Runner will be director Brad Furman's third film. He directed The Take, starring John Leguizamo, Tyrese Gibson and Rosie Perez and The Lincoln Lawyer, starring Matthew McConaughey, Ryan Phillippe, William H. Macy and Marisa Tomei.

The team of producers includes Leonardo DiCaprio. Christophe Beck composed the score. His experience includes The Hangover, Pitch Perfect, The Internship, R.I.P.D., The Watch, The Guilt Trip and The Muppets.
