Working on their latest film, Justin Timberlake was seen chatting with Ben Affleck on a basketball court's sideline while filming their new movie "Runner, Runner" in Puerto Rico today (July 23).
The "Good Will Hunting" actor and writer sported a red and yellow "Jaco" uniform with black tennis shoes while the "Social Network" star worked the sidelines in a striped button-down dress shirt and dark pants.
The movie stars Timberlake as a man who loses his college tuition cash by playing online poker. He travels to the poker site's home Costa Rica in order to win back his money from site owner, played by Affleck.
Every leading man needs a leading lady and 26-year-old British actress Gemma Arterton will fill the role in this film. "Runner, Runner" is scheduled for release sometime in 2013.
