The Wagner/Cuban Company's Magnet Releasing, genre arm of Magnolia Pictures, announced today that they have acquired world rights to Honeymoon, the chilling directorial debut from Leigh Janiak, which had its world premiere at SXSW earlier this month.

Honeymoon features rising star Rose Leslie (HBO's Game of Thrones, Downton Abbey) and Harry Treadaway (The Lone Ranger, Penny Dreadful). Janiak co-wrote the film with Phil Graziadei; Patrick Baker and Esmé Howard produced.

Leslie and Harry Treadaway star as young newlyweds who travel to remote lake country for their honeymoon where the promise of private romance awaits them. Shortly after arriving, Paul finds Bea wandering and disoriented in the middle of the night. As she becomes more distant and her behavior increasingly peculiar, Paul begins to suspect something more sinister than sleepwalking took place in the woods.

Christina Rogers and the Magnolia Pictures International team will be representing the film at the upcoming Marché du Film in Cannes. All international rights are available.

Honeymoon will next be featured at the Tribeca Film Festival in April. Magnet will release the film later this year.

Here's what Magnolia President Eamonn Bowles had to say in a statement.

Honeymoon is an auspicious debut from the very talented Leigh Janiak, who has a preternatural mastery of tone and mounting dread, not to mention a deft hand with actors. Rose Leslie and Harry Treadaway have stunning chemistry-they light up the screen."

Director Leigh Janiak had this to say in his statement.

"I feel incredibly honored to have my first feature in Magnet's smart and expert hands. I'm so excited to work with them-they're the perfect home for the film, and I know they will do great things with it."
