Peter Jackson gave Andy Serkis filmmaking tips while the pair were shooting 'The Hobbit', which sees the actor make his directorial debut.
'The Lord Of The Rings' director helped Andy - who voices sly goblin-like creature Gollum in the film franchise - make his directorial debut as a second unit helmer on 'The Hobbit: An Unexpected Journey', and Peter monitored his progress closely on set.
Andy said: ''He would watch form his set, call: 'No, no, it's not working. Just bail out of the shot.' He was mentoring me.
''There were different ways we worked. We'd set up entire sequences, or he'd start a scene and I would finish it if there wasn't time.''
The British actor was stunned to receive an email from Oscar-winning director Peter last year, asking him whether he would like to help helm the motion picture.
He added to Empire magazine: ''Pete's known that I have wanted to direct for many years and he's always been very encouraging.
''I was just going to come over [to New Zealand] and do Gollum, and then get on with my life. This wasn't part of The Game plan.''
The long-awaited first part 'The Hobbit: An Unexpected Journey' is scheduled for release in December.
