Zac Efron Struggled To 'Separate' Himself From Ted Bundy Character: 'It Was Almost Impossible'

Zac Efron hit the red carpet for the London premiere of 'Extremely Wicked, Shockingly Evil and Vile.'

While speaking to reporters prior to the screening of the film, which follows the story of serial killer Ted Bundy, Efron revealed that he found it difficult to let go of his character when not working.

"I've never played a role in which I really have to separate myself from when I go home at night and it was almost impossible. I'd like to say that I did it successfully but I couldn't," Efron said on the red carpet.

He went on to defend the biopic after many felt that it would "romanticise" cold-blooded killers such as Bundy, who was renowned for being conventionally attractive and charming, which contrasted sharply to society's image of a serial killer at that time.

"I really wasn't interested in playing a serial killer. I'm not in the business of glamorising a horrendous person or his acts, but there is something unique about the way we went into the psyche of Ted, and his longtime girlfriend Liz," he added.

He continued, "It's a different perspective and not your run-of-the-mill serial killer cliché, body count gets higher and higher and the guy you always knew did it, did it. This is what it was like to be there on the day, we didn't know if he was innocent or guilty, we just saw Ted Bundy through their eyes."

Efron stars alongside Lily Collins, who plays his longtime girlfriend Elizabeth, who refused to believe the truth about him for years. The film is also portrayed from her perspective.

Extremely Wicked, Shockingly Evil and Vile comes out on Netflix on May 3.
