Zac Efron will be appearing on The Graham Norton Show tonight to talk about a chilling new role hes playing; Ted Bundy.
His new film, Extremely Wicked, Shockingly Evil and Vile, looks at the life of the serial killer, and how those around him reacted to what he did.
In particular, it shows the perspective of former long-term girlfriend of Bundy, Elizabeth Kloepfer, played by Lily Collins.
It will also see Kaya Scodelario in the role of the killers ex-wife, Carole Ann Boone, and John Malkovich as Edward Cowart, the presiding judge at Bundys trial.
With it set for release very soon, lets take a look at who Ted Bundy was.
The real Ted Bundy
Theodore Robert Bundy was an American serial killer, kidnapper, rapist, burglar, and necrophile.
He was born on 24 November 1946 in Vermont, and later spent time in Philadelphia, Washington, and Utah.
Bundy is known for the many brutal murders he carried out, the number of which is at least thirty, although the total has never been confirmed.
His earliest documented homicides were committed in 1974 when he was 27 years old. During this time, women had been going missing in the Olympia area, and Bundy was working for a state government agency involved in the search for them.
It was not until August 1975 that he was arrested, but his crimes did not stop there. He escaped jail twice, the second time getting to Florida and attacking and murdering more women.
This was when news spread of the sickening acts hed carried out, with the world becoming shocked that someone could do such things.
He violently killed his victims, before revisiting their bodies and sexually assaulting them as they decomposed, and decapitated some of the women, keeping their skulls in his apartment as mementos.
Bundy was executed in the electric chair at Florida State Prison on 24 January 1989, and the title of the new film is based off of what the judge called the sadistic killer as he was sentenced to death.
