Zac Efron channels serial killer Ted Bundy in 'Extremely Wicked, Shockingly Evil and Vile' trailer

The first official trailer for the Ted Bundy biopic, "Extremely Wicked, Shockingly Evil and Vile," was released on Friday.

The movie, directed by filmmaker Joe Berlinger, stars Zac Efron as serial killer Ted Bundy, and centers on Bundy's relationship with his girlfriend, Liz Kloepfer, played by Lily Collins.

Voltage Pictures released the trailer one day before it premiered at the Sundance Film Festival on Saturday. A nationwide release date has not been set.

The trailer came out a day after Netflix released its four-part docuseries, "Conversations with a Killer: The Ted Bundy Tapes," which also was directed by Berlinger. It featured archival footage and never-before-heard audio recordings.

Bundy confessed to killing more than two dozen women and was executed in Florida in 1989.
