Daniel Radcliffe is not expecting to reprise his role as Harry Potter, despite the publication of JK Rowling's follow-up story about the wizard's later life.

The 24-year-old actor shot to fame after being cast as the boy wizard aged 11 and played him on screen in all eight film adaptations of Rowling's seven books about Harry and his friends' adventures at Hogwarts school.

The author has just revived the character in a 1,500-word story published on her Pottermore website, following Harry and his friends Ron Weasley, Hermione Granger and wife Ginny Weasley - played by Rupert Grint, Emma Watson and Bonnie Wright in the film - set 16 years after they graduated from Hogwarts.

Asked if fans can expect a film version, Daniel told reporters, via satellite from New York, during the Television Critics Association summer press tour: "My inclination is to say 'no' because I don't think it's even a hypothetical at the moment.

"What she's written - and I haven't read yet but I will - I understand it's a very short piece. And he's 12 years older than I am now."

Since the Harry Potter films ended, Daniel has played a variety of roles, from beat poet Allen Ginsberg in indie film Kill Your Darlings, to hunchbacked assistant Igor in an upcoming remake of Frankenstein and a variety of stage roles including a musical. And in TV show A Young Doctor's Notebook he plays a radical doctor, opposite Jon Hamm, who plays an older version of the same character.

Asked if the latest stage of his career was a reaction to his time as a child actor, Daniel replied: "I think it is connected to Potter, but maybe not in the way everyone thinks.

"What it is, I played only one character for such a long time, I think there's a little bit of envy and desire to try as many different things as possible. Now that I'm in that position, I'm trying to while the getting is good."
