Sony Pictures Worldwide Acquisitions has picked up all North American rights to Magnet Films’ thriller “Retreat,” which stars Cillian Murphy, Thandie Newton and Jamie Bell.

SPWA’s Lia Buman and Dan Primozic brokered the deal with Magnet’s Gary Sinyor and Simon Crowe of SC Films, which will handle worldwide sales on behalf of Quickfire Films.

Carl Tibbetts makes his feature directorial debut on the film, which finds Murphy and Newton heading to a remote island cottage to rebuild their frail marriage. When a wounded and armed stranger (Bell) shows up at their door with news about a deadly airborne virus, they must seal themselves inside the cottage, where the tension starts to escalate from psychological to physical.

Sinyor is producing for Magnet, whose Sir David Frost and Michael Rosenberg will exec produce along with Dominic Wright and Jacqueline Kerrin of Ripple World Pictures.

“I’m delighted that Sony have added North America to the territories they held before we started filming” said Sinyor. “The film is a very successful realisation of a really strong script loaded with twists and turns and with great performances from our cast. It looks incredibly cinematic and we all look forward to working with Sony to see it up on the big screen.”
