It's only a matter of weeks before the release of The Hobbit : An Unexpected Journey and recently Ian McKellen spoke out about how of having to act on a green screen reduced him to tears.

McKellen who will reprise his role of wizard Gandalf in the film revealed he found it difficult to shoot scenes this way so much he threw a tantrum on set.  'In order to shoot the dwarves and a large Gandalf, we couldn't be in the same set,' he said. 'All I had for company was 13 photographs of the dwarves on top of stands with little lights – whoever's talking flashes up. Pretending you're with 13 other people when you're on your own, it stretches your technical ability to the absolute limits.' 'I cried, actually. I cried. Then I said out loud, 'This is not why I became an actor'. Unfortunately the microphone was on and the whole studio heard'.

 However order was restored the following day when he arrived at the studio hand found everything had been made pleasant, he said 'The next day I went into my little tent and it had all been decorated beautifully. Remnants of Rivendell, carpets and cushions, fresh fruit and flowers, things that were hanging. It was lovely'. Its a tough life being an actor!

The Hobbit is released on the 13th December.
