The actor made the comments while he was attending the controversial film’s premiere in London, according to the Mail Online.
“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,” he said. “I’d like to say that I did it successfully but I couldn’t.”
He added that Bundy was not a role he had ever imagined himself taking: “I really wasn’t interested in playing a serial killer,” he said.
“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 [played by Lily Collins].
“It’s a different perspective and not your run-of-the-mill serial killer cliché, body count gets higher and higher and oh 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.”
Extremely Wicked, Shockingly Evil and Vile is released in cinemas and on Sky Cinema on 3 May.
