NEW YORK—Popular girl/girl performer and Penthouse Pet Ryan Keely shares billing with writer/director M. Night Shyamalan in a new short by MTV lampooning the upcoming Shyamalan-conceived horror film Devil.

Titled Escalation, the spoof depicts Shyamalan, MTV's Josh Horowitz and Keely getting "trapped" on an escalator and panicking. (In Devil, a group of strangers enounter a satanic presence on a stuck elevator.)

"I was humbled, honored and excited to work with Josh Horowitz and M. Night Shyamalan," Keely said. "I don't think I've ever laughed so hard in one afternoon. Making the spoof was an unforgettable experience."

Devil comes to theaters Sept. 17. See the Escalation short here.
