Kill Your Darlings director reveals Daniel Radcliffe's extreme commitment to sex scene

Dane DeHaan as Lucien Carr and Daniel Radcliffe as Allen Ginsberg in Kill Your Darlings.

Actors always talk about how awkward it is to get naked and film sex scenes in movies.

But director John Krokidas has revealed Daniel Radcliffe was prepared to do whatever it took to nail his gay sex scene in the 2013 flick Kill Your Darlings.

In his first major role post-Harry Potter, Radcliffe played prominent gay writer and poet Allen Ginsberg as a young college student.

Talking to Vulture, Krokidas said the thought of not including Ginsberg's sexuality in the film felt like a "crime".

And he says Radcliffe was more than committed to getting the scene perfect.

"[He had] no issue doing the scene whatsoever," Krokidas said. "His only question was, 'Just so I know, how naked do you want me to be - movie-naked or Equus-naked?'

"I said, 'I hate when people block sex scenes in order to play hide-the-genitalia - that feels so forced. So let's just block it, and if it falls into frame, we'll shoot it'."

Thinking about the nudity further, Krokidas realised a rather large inconsistency may get in the way. But Radcliffe was quick to dismiss it.

"But then I remember going, 'Oh sh*t: You're British, and Allen Ginsberg is one of the most famous Jews of the 20th century. On second thought, I don't think we're going to go Equus-naked.'

"And Dan said, 'John, my mother's Jewish, and I'm circumcised. Play the scene any way you want.' God bless Daniel Radcliffe - he commits to all of his actions."

Of course, it wasn't Radcliffe's first time revealing all to an audience. He famously stripped nude as a 17-year-old when he appeared on Broadway in the play Equus.
