The book is a follow-up of the Harry Potter franchise.
The 'Kill Your Darlings' star said that it's the version of the flick that he would be most interested in, adding that he likes the idea of an intertwining storyline, the Daily Express reported.
The 24-year-old actor asserted that he could be talked into the role.
Radcliffe had previously told a US publication that he will not rule out appearing in the follow-up franchise because he never knows what Rowling is going to write.
