Swedish stunner Mercedes Masöhn (“The Finder”) and Robert Buckley (“One Tree Hill”) are the latest to be cast in the ABC pilot “666 Park Avenue,” a new supernatural drama based on the book series by author Gabriella Pierce.

“666 Park Avenue” is set in a historic Manhattan apartment building where demonic forces are having their way with the tenants. Masöhn plays fashion photographer Louise. Buckley is her playwright boyfriend Brian.

Costars include Terry O’Quinn (“LOST”) as the building’s owner and Rachael Taylor (“Charlie’s Angels’) and Dave Annabel (“Brothers & Sisters”) as its new supers. The show is produced by writer David Wilcox (“Fringe”), Warner Bros. TV and Alloy Entertainment.

Masöhn last starred as a courageous flight attendant in writer/director John Pogue’s viral outbreak thriller Quarantine 2: Terminal. She can currently be seen on the Fox TV “Bones” spinoff “The Finder.”
