“Westworld” alumna Angela Sarafyan is joining the growing and intriguing cast of director Joe Berlinger’s upcoming Ted Bundy biopic, Extremely Wicked, Shocking Evil, and Vile. The film tells Bundy’s tale from the perspective of his longtime girlfriend Elizabeth Kloepfer.

Berlinger, the noted documentary filmmaker behind Metallica’s Some Kind of Monster and the Paradise Lost true-crime docs, is working off a script by new scribe Michael Werwie. Zac Efron (Neighbors) portrays Bundy and Lily Collins (The Mortal Instruments: City of Bones) plays Kloepfer.

Sarafyan will play Kloepfer’s friend Joanna, who makes her suspicious of Bundy’s actions. She co-stars alongside John Malkovich (Red), Jim Parsons (“Big Bang Theory”), Haley Joel Osment (Sixth Sense), Kaya Scodelario (Pirates of the Caribbean: Dead Men Tell No Tales), Jeffrey Donovan (“Burn Notice”), Grace Victoria Cox (“Heathers”), Dylan Baker (Happiness), and Metallica’s James Hetfield.
