Daniel Radcliffe Is ‘Phenomenal,’ Elizabeth Olsen Raves

'Martha Marcy May Marlene' actress is getting ready to star opposite Radcliffe in the thriller 'Kill Your Darlings.'

PARK CITY, Utah — Daniel Radcliffe is no longer just the Boy Who Lived — at this stage, he’s the Man Who Flourished.

Indeed, Radcliffe has kept his post-”Potter” career very interesting, what with a turn as a horror lead in next month’s “Woman in Black,” a lengthy run on Broadway in “How to Succeed in Business Without Really Trying” and even a hosting stint on “Saturday Night Live” earlier this year.

He’s set to keep his fans guessing even further with his next confirmed movie, “Kill Your Darlings,” which tells the tale of how Beat Generation icons Allen Ginsberg, Jack Kerouac and Lucien Carr first met — and how that meeting eventually led to murder.

Radcliffe plays Ginsberg in the film, and starring opposite him is up-and-coming actress Elizabeth Olsen. The brilliant young star of “Martha Marcy May Marlene” spoke with MTV News about joining the cast of “Kill Your Darlings,” making her admiration for the “Harry Potter” star very well-known.

“He is so phenomenal,” Olsen said at the Sundance Film Festival, where she’s repping the paranormal thriller “Red Lights.” “He’s an incredible person. He’s so funny and smart and fun. He’s such a good guy.”

Olsen is just one small cog in the greater machine of “Kill Your Darlings,” according to the actress. She said she only appears in “three scenes of that movie” as Edie Parker, girlfriend of Jack Kerouac.

“Edie Parker is the one who introduced Ginsberg to Lucien Carr and Jack Kerouac,” she explained of her role. “She’s kind of the glue between them. I’m just there for a few scenes to explain that part of the story. But her personal life is really, really incredible.”

The 2012 Sundance Film Festival is officially under way, and the MTV Movies team is on the ground reporting on the hottest stars and the movies everyone will be talking about in the year to come. Keep it locked with MTV Movies for everything there is to know about Sundance.
