Zac Efron is turning heads with his take on Ted Bundy in Netflix’s new true crime film “Extremely Wicked, Shockingly Evil And Vile”.

Efron, 31, put a lot of emphasis on embodying his role as the infamous serial killer. “I lost a lot of weight for the role,” he told Entertainment Weekly. “On all the footage I could see Ted was always, not emaciated, but was kind of a ’70s sinewy-buff.”

“I worked to learn how to talk with new teeth in, I completely went on my exercise bike every morning, and would watch kind of heavy stuff,” Efron continued. “We spent a lot of time in jail. And I officially know that’s as much time as I want to spend there. It was only a couple of hours, but it’s shocking.”

It took a lot of effort for Efron to separate himself from the very-real character he was playing. “I did breathing and meditation. I think that’s the only way,” he shared. “I really love TM, transcendental meditation. I did TM on the way home.”

“Really, you can’t ever really let go of all of it,” expressed “The Greatest Showman” actor. “There’s always a little bit of you that knows tomorrow you’re Ted.”

Speaking of “The Greatest Showman”, Efron’s latest project presents a completely different vibe than his highly-applauded musical with Hugh Jackman. “Let’s just say it was different than ‘The Greatest Showman’ set,” he said. “The demeanour was very thoughtful and serious.”

“The process of filmmaking is always, always an adventure,” Efron continued. “I was with careful people. I continue to push myself to try new things and push the envelope with an acting career that I kind of stumbled onto. It’s kind of a rite of passage.”

Netflix’s “Extremely Wicked, Shockingly Evil And Vile” premiered Jan. 26 at Sundance Film Festival ahead of its global premiere on May 3.
