The 23-year-old confirmed that he is committed to the role, reported Digital Spy.
"If I remember correctly, the script said, 'Frankenstein By Max Landis, Based On (The America Popular Culture Zeitgeist Interpretation of) Mary Shelley's Frankenstein'.
"It's far and away the best script I've read coming out of a big studio in the time that I've been off Potter. It's definitely going to be unusual," he said.
Radcliffe also spoke about his role in new movie "Horns".
"I think it has the potential to capture something in people's imaginations. It's a crazy story, but it's really compelling."
Radcliffe has also been cast in new film "Tokyo Vice".
