Radcliffe, 24, will be seen playing late Beat poet Allen Ginsberg in "Kill Your Darlings," set for release in U.S. theaters Oct. 18.
"I was struggling in vain to not come close to making a face that would make people think of Harry," Radcliffe told this week's New York Times Magazine about starring in his 19th-century horror movie "The Women in Black" -- one of his first post-Potter projects.
So, what precisely is a Harry face?
"There isn't," Radcliffe said. "It's just my face. I have to accept the fact that my face is going to remind people of Harry because I played that character. If I try to avoid being expressive in that same way, all I'll do is stop being expressive, and I won't be any farther away from that character."
