Daniel Radcliffe: I'm Grateful To Harry Potter Books
Star selects JK Rowling's first Potter novel as his favourite book...
The actor was quizzed about his favourite book by kids' book publisher Scolastic as part of the Read Every Day campaign - and plumped for Harry Potter And The Philosopher's Stone.
He said: "It would be churlish of me not to say that it was the book that gave me everything I have."
Meanwhile Louis Tomlinson from One Direction had no pretensions when asked for his favourite, choosing David Beckham's Soccer Skills.
Louis was recently injured in a charity football match.
And his 1D bandmate Harry Styles selected Michael Buble's autobiography Onstage, Offstage.
