Pretty Little Liars

Janel Parrish and Brant Daugherty in Something Wicked: First Look at Horror Short! (PHOTOS)

Janel Parrish (Mona) and Brant Daugherty (Noel Kahn) have had their twisted chemistry on Pretty Little Liars, but now they're taking the evil to a whole new level.

The PLL co-stars are working on a Fall 2013 horror short written by Jordan Ross called Something Wicked. According to the Facebook page, the film is "about the darkness we all have inside of us and what we choose to do with it."

Read on for more details on the short and then click through the gallery to get a first look at Janel and Brant covered in fake blood for a photoshoot.

Nothing is as it seems after Aidan (Brant Daughtery) saves Ronnie (Janel Parrish) from a dangerous encounter. "Something Wicked" is an original horror short that zeroes in on our predisposition of evil and who we become when we face it.
