Topher Grace put a lot of trust in Spike Lee when he was cast as Ku Klux Klan leader David Duke in “BlacKkKlansman”.

Appearing on “The IMDb Show”, the former “That ’70s Show” star spoke about his audition to play the infamous KKK leader in the Oscar-winning film.

It’s a terrible character but it’s a juicy role. I mean I was dying to play it!” Grace admitted. “The night before, I’m sitting in my office at home and my wife and daughter are asleep and it’s literally just me alone in a room and I can’t say the words… like I’m trying to rehearse the script saying these lines and then swallowing these words which the character obviously… he’d definitely relish saying them.”

The actor continued, “The next day I went in to meet Spike for the first time and I said, ‘Hey man I am so uncomfortable reading this material’ and he immediately went to work on making me feel comfortable.”

Asked how Lee made him feel comfortable enough to say such awful, racist things, Grace recalled, “He kind of said like ‘don’t worry I’m Spike Lee’ I mean he didn’t say that exactly but the tone of what he was saying… it’s like there really is only one filmmaker you could do this for and it’s him and he’s right.”

Grace also said that when he finally got the role, he decided to do research by purchasing Duke’s autobiography on Amazon.

Amazon was like ‘did you mean to order that?’ Grace laughed, and then described his recommendations on the online store getting “very weird” after that.
