Ahead of its shooting start next month, Sean Penn-starrer The Gunman has virtually sold out for Studiocanal in Cannes, Deadline said.

This is the project from producers Joel Silver and Andrew Rona that Studiocanal is fully financing. Taken helmer Pierre Morel is directing the action film, which previously went by the title Prone Gunman.

Silver and Rona are also in business with Studiocanal on the upcoming Jaume Collet-Serra-directed Non-Stop, which Universal is releasing Stateside. Footage from that film was screened for buyers in Cannes, which Studiocanal says helped fuel sales on The Gunman. Morel was also in town to enthuse buyers.

The movie sees Penn as an ex-government contract killer whose past comes back to haunt him.
