Atom Tickets has rolled out a new promotion where people born on the 14th day of any month can get a ticket to the Nicolas Cage movie Longlegs for free. Why the 14th? The serial killer in the movie targets people born on the 14th.

You can visit the Atom Tickets website and use the code BIRTHDAY14 to get a free ticket. You can claim only one ticket, and the fine print says your ID may be verified. The offer runs through August 4 or while supplies last.

Longlegs is a horror-thriller from writer-director Osgood Perkins (Gretel & Hansel). The film follows an FBI agent hunting down a serial killer. The cast includes Maika Monroe, Kiernan Shipka, and Cage.
