Zac Efron as Ted Bundy in 'Extremely Wicked, Shockingly Evil and Vile' trailer will give you the chills

Actor Zac Efron's transformation into notorious serial killer Ted Bundy is absolutely terrifying in his new film 'Extremely Wicked, Shockingly Evil and Vile'. Netflix gave us a glimpse of Efron's character as it premiered the film's first trailer ahead of its debut on the streaming service in May. 

The film, a thriller, follows the life of Bundy and is narrated through the perspective of his girlfriend, Elizabeth Kloepfer, who struggled to accept the reality of her boyfriend’s true nature.

Kloepfer's character is played by 30-year-old Lily Collins, while John Malkovich plays Edward Cowart, the presiding judge at Bundy’s 1979 trial in Florida who sentenced the killer to death.

The film opens May 3 in select theaters and on Netflix.

Bundy, who was a law student, was convicted of raping and killing multiple women across seven states in the country from 1974 to 1978. Bundy, who famously described himself as "the most cold-hearted son of a bitch you’ll ever meet", met Kloepfer in 1969 in Washington where she worked as a secretary at the University of Washington School of Medicine.

The killer reportedly used to decapitate his victim to take their heads back to his apartment to keep as a souvenir. He would also sometimes spend the night with a corpse and was also known to re-visit sites where he had dumped his victims' bodies to have sex with them. 

When he was once questioned about the horrifying souvenirs he kept at his home, he replied: "When you work hard to do something right, you don’t want to forget it."

Bundy was eventually executed on January 24, 1989, after confessing to 30 homicides. The real number of his killings is still not known, however, it is estimated that he murdered at least 100 women during his killing spree, making him the deadliest serial killer the US has ever known.
