Daniel Radcliffe and Dane DeHaan in ‘Kill Your Darlings.’

Daniel Radcliffe appeared nude on Broadway so what’s the big deal about a little gay sex in his latest film “Kill Your Darlings?” His plays Beat poet Allen Ginsberg in his latest envelope-pushing career move.

Radcliffe, who starred for ten years as wizard Harry Potter, scored his first post-Potter role in horror film “The Woman in Black.”

But his most publicized role, until now, was in they play Equus, both on Broadway and London’s West End. He played a boy who sexually fantasized about a horse. The role called for him to be totally nude on stage in several scenes.

In his latest film, screened last night (Jan. 18) at the Sundance Film Festival, he plays a young Ginsberg who is just beginning to explore his sexuality with the aid of booze and drugs.

The film focuses on the Beat Generation murder of David Kammerer at the hands of Lucien Carr, a gifted student and friend of Ginsberg’s, Beat writers William Burroughs and Jack Kerouac. Ben Foster plays Burroughs and Jack Houston is Kerouac.

The murder was rooted in gay sexual obsession that Kammerer had for Carr, which Carr repeatedly rejected. Kammerer stalked Carr leading to a confrontation during which Carr stabbed and killed him.

As a young Ginsberg, Radcliffe’s scenes include oral sex, making out and getting naked for sex, all with men.

“It was something new,” Radcliffe said after the screening. “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.”

He says he got to know his scene-mate, which helped with filming.

“We were able to hang out a little bit on set and get to know each other a little bit, which I think is important when you’re doing a scene so intimate,” Radcliffe said. “You have to feel like you’re both in it together.”

Radcliffe said he was surprised to discover that girls were turned on by his scenes. Check out Dan’s red carpet interview at Sundance and be sure to follow TheImproper on Twitter for the latest Sundance updates.
