Zac Efron has released the first image of himself in character as Ted Bundy as production gets underway on the highly-anticipated movie about the infamous serial killer.

The actor, 30, uploaded to Instagram a black and white photo from the set of Extremely Wicked, Shockingly Evil and Vile, showing him posing in front of cameras wearing a plain white T-shirt and pants, with a thick moustache.

He captioned it simply: "Meet Ted. #BehindTheScenes"

Efron's casting as Bundy in the psychological thriller is his first foray into darker movies. With the exception of drama The Paperboy in 2012, he's largely only appeared in musicals and comedies — including The Greatest Showman, Bad Neighbours, 17 Again, High School Musical and Baywatch until now, reports News.com.au.

Extremely Wicked focuses on Bundy, who escaped from prison twice and confessed to at least 30 murders before he was executed in 1989.

The story is told from the perspective of his longtime girlfriend, Elizabeth Kloepfer (played by Lily Collins), who kept dating Bundy despite mounting evidence linking him to the disappearance of a number of young women in the 1970s.
