Thanks Sparky. And thank you to everyone else who has shared suggestions for further reading so far, I have already been able to make a list of interesting books to read next. I have just finished reading 'This much is true' by Miriam Margolyes, which I enjoyed but I hesitate to recommend unreservedly as it a little overlong and contains a great deal of bottom and sexual references which, in my opinion do not add much. However, there is a great deal of fascinating insight into the world of professional acting and Miriam does not pull her punches and is refreshingly frank about who she likes and dislikes. What finally sold it to me, were the photos and the index both of which I think are essential, but not always present, in a biography or autobiography.
