Never having worked with him long term, only odd days here and there, albeit I do know a little more about him than he would tell. In fact, not too interesting or amazing that this so called English gentleman did not mince his fruity language and when he thought it was necessary, the expletives ad infinitum were well rehearsed and presumably sometimes served their desired purpose, which was at times simply to avoid someone forcing him, or cajoling him to do something at times that may have been inconvenient for him?
He was rather full of himself and certainly most ordinary film crew were of little or no consequence as regards any pleasantries.
That said, of course many actors were similar, the late Nicol Williamson being one example. Bearing in mind, Mr Williamson, with whom I did work, was an absolute actor down to every detail and attention to perfection, which is a far cry from Mr Moore. For anyone unaware, Mr Williamson was a trained Shakespearean and therefore carried himself through his professional life, regarded with much respect, albeit I feel he was unappreciated, due in part to modesty and possible shyness from the publicity he did not yearn.
