Another new release opened in the third slot: crime drama “Runner Runner,” starring Justin Timberlake as a Princeton grad student who travels to Costa Rica to confront a tycoon, played by Ben Affleck, he believes has taken him for a ride on an online poker site.

The film directed by Pedro Pablo Ibarra debuted in the US and Canada with $2.5 million in ticket sales.
