Actor Daniel Radcliffe says he was given “step-by-step” direction while filming a steamy gay sex scene in the film Kill Your Darlings.

Radcliffe (Harry Potter) plays gay beat generation poet Allen Ginsberg in John Krokidas' thriller Kill Your Darlings, which premiered in January at the Sundance Film Festival in Park City, Utah.

In an appearance on the BBC's The Graham Norton Show, Radcliffee told host Graham Norton that Krokidas gave him “step-by-step instructions.”

“I was doing a gay sex scene and the director [Krokidas] was giving me step-by-step instructions,” Radcliffe said. “And the favorite note I have ever had was when we were kissing and the director shouted, 'Not like that. Crazy sex kissing!'”

Earlier, Radcliffe told E! Online that Krokidas put him at ease while filming the scene.

“It was something new,” he said. “But you know what? We shot that whole scene in maybe an hour and a half so it was incredibly fast-paced. I didn't really have time to stop to think and worry about it.”

“John was very helpful in furnishing me with a lot of graphic detail of what I would be experiencing at the various stages,” he added with a laugh.
