Zac Efron Transforms Into Ted Bundy In Trailer for 'Extremely Wicked, Shocking Evil and Vile'

We've never seen Zac Efron quite like this before.

The actor ventures out of his comfort zone in the first trailer for "Extremely Wicked, Shocking Evil and Vile," where he'll play infamous serial killer Ted Bundy.

Bundy brutally murdered and assaulted at least 30 women before he was caught in 1978. His trial became a media circus as he attempted to defended himself in court, won the support of female fans and even proposed to his girlfriend while she was testifying in his in favor. (FYI: She said yes) Bundy was executed in the electric chair in 1989.

The movie is told from the perspective of one of Bundy's ex-girlfriends, Liz Kloepfer (Lily Collins), who comes to the horrific realization that the man she loves could actually be a vicious killer.

Based on the sneak peek, the film will chronicle Bundy's murder spree (fake arm sling and all), as well as his arrest, escapes (yes, he escaped custody twice) and trial. Kaya Scodelario also appears in the footage as Carole Ann Boone, the woman who married him while on trial.

The movie is directed by Joe Berlinger, who also created and directed the new Netflix docuseries "Conversations with a Killer: The Ted Bundy Tapes."

"Extremely Wicked, Shocking Evil and Vile" premieres at Sundance this weekend.
