Zac Efron and Lily Collins premiere new Ted Bundy movie in London

A platinum-blonde Zac Efron was in London Wednesday (24 APRIL 2019) to premiere his new movie, "Extremely Wicked, Shockingly Evil and Vile," about notorious real-life serial killer Ted Bundy.

Efron, who stars as the infamous killer, was joined on the carpet by co-star Lily Collins, who plays Bundy's former girlfriend, Elizabeth Kloepfer.

To prepare for the role, Efron studied court footage and archive interviews of Bundy, while Collins personally met with Kloepfer.

"For me, that was a huge gift, to be able to meet the woman whose story this is and her daughter and she gave me such inspiration because she brought me all these old photos and love letters. So to be able to have her blessing going forward with this and her support was really, really necessary and just kind of good karma just around the project," said Collins.
