Ian McKellen has confirmed that he will reprise his role as Gandalf in the two-film adaptation of JRR Tolkien's 'The Hobbit'.

The 'Lord of the Rings' star told Empire magazine that it was not a part to turn down.

When asked if he was returning, the actor said: "Yes, it's true."

"Obviously, it's not a part that you turn down, I loved playing Gandalf."

Speaking about the second film, he said: "Well I've read 'The Hobbit' so I've got a good idea of what the story would be."

"But as to how it's going to work over two films and what's going to happen on screen, well Guillermo [del Toro, director] has not got down to working out the major details yet - I can tell you it's going to be amazing though."
