THE Australian director of the international self-help phenomenon The Secret is suing its creator Rhonda Byrne for $150 million.

The director Drew Heriot claims he is owed the money from Ms Byrne, originally from Melbourne, for the popular straight-to-DVD movie and the best-selling self-help book on which it is based.

Ms Byrne has been working overtime to repel the negativity emanating from a series of lawsuits over her huge money-spinning life guide.
