He's shot three films due to come out in the next year. "Kill Your Darlings," which premiered at the Sundance Film Festival in January, stars Radcliffe as Ginsberg - Beat poetry, gay sex scenes and all. Radcliffe says he's never been prouder of a piece of work.
He's also filmed "The F Word," which he calls a "very funny, very sweet but also very smart" romantic comedy from Canadian director Michael Dowse.
"I don't want to say (I'm) playing myself, exactly," Radcliffe said, "but (I'm) playing a character that's fairly high-anxiety, slightly hyperactive guy."
He's especially excited about "Horns," a film by French horror auteur Alexandre Aja ("The Hills Have Eyes," "Piranha") about a bereaved man who grows devilish horns that allow him access to the thoughts and feelings of others.
"It's a love story, it's a revenge movie, it's a horror movie in parts - it's going to be crazy," said Radcliffe, who made an earlier foray into horror movies with "The Woman in Black."
Next up, he will star as mad-scientist's assistant Igor in Max Landis' pop-culture spin on the "Frankenstein" story.
All in all, it's an eclectic list of projects. Radcliffe says there is a philosophy guiding his career choices, but "it's very basic. It's just what excites me. It's what gets me interested."
"Hopefully later on this year, people will start to see some very different performances from me. And hopefully some really good movies," he said. "It's about the movie as a whole, not just people studying my performance and seeing how I'm getting different and how I'm growing up."
Radcliffe accepts that fascination with how he's growing up is unlikely to fade altogether. But he seems comfortable with the Harry Potter legacy, happy to have made the often tricky transition from child star to adult actor.
The "Harry Potter" movie-makers have been praised for creating a stable creative home for their young stars, who went from preteens to adults over the course of eight films released between 2001 and 2011.
"I feel like everyone wanted Potter to be more of a handcuff than it actually was," said the resolutely well-adjusted Radcliffe.
"I think Harry Potter is going to be around for a while - a long while - but as long as it doesn't inhibit me getting parts in the present time then it's fine. It's a lovely association to have because it's something I'm incredibly proud of.
"People always say, 'Don't you just want to forget about it?' No! That was my entire adolescence."
