Zac Efron as Ted Bundy in Extremely Wicked Trailer

We finally get our first glimpse at Zac Efron as real-life serial killer Ted Bundy in the chilling new trailer for Extremely Wicked, Shockingly Evil and Vile, released Friday.

It shows Efron as a witty, charming killer with a deadly secret.

Directed by Joe Berlinger, Extremely Wicked, Shockingly Evil and Vile promises to reveal “the story behind America’s most notorious serial killer,” as seen through the perspective of Bundy’s longtime girlfriend, Elizabeth Kloepfer (Lily Collins).

“There are things you don’t know … that will shock you beyond your worst nightmare,” Efron says in a voiceover in the trailer.

Bundy, who assaulted and murdered numerous girls and women in the 1970s, confessed to 30 homicides in seven states between 1974 and 1978 before he was executed in 1989.

As part of Efron’s research, he spent some time talking to people who knew Bundy. “A lot of them were shocked,” Efron told Variety.

“They could not believe that such a strait-laced, pleasant, smart, smiling, calm individual was responsible for such horrendous, horrific crimes. And that makes him all the more fascinating because really he was loved by nearly everyone around him. Even people in prison enjoyed their time with Ted Bundy.”

John Malkovich portrays Judge Edward Cowart, who presided over Bundy’s trial and sentenced him to death, while Jim Parsons plays lead prosecutor Larry Simpson.

Extremely Wicked, Shockingly Evil and Vile will have its world premiere at Sundance today (January 26, 2019).
