Tom Shadyac's I Am: Hollywood finds its heart

12 September 2013 Last updated at 00:00 BST

Tom Shadyac was a Hollywood director who had it all - the 1994 comedy Ace Ventura: Pet Detective thrust him into the spotlight and he went on to make six more films.

Collectively, his movies earned more than $2bn (£1.3bn) but then he became disillusioned and began to give up his material gains.

He developed a new philosophy to life, which is articulated in his book, Life's Operating Manual, and in a documentary - I Am.

Talking Movies' Tom Brook caught up with him.
