Laurence Olivier spoke of his early days in film, and the transitions back and forth between theater and the soundstage.
" At that time, stage and film acting were thought of as two entirely different crafts.even professions. We know now that is not by any means a true assessment; the truth is infinitely subtler. They call for the same ingredients in different proportions. The precise differences may take some years of puzzling work to appreciate: in each case there are many subtle variations according to the character of the actor. It took me years to learn to film act; at least ten of these were appallingly rough and ready, from sheer prejudice and ignorance. After that, it was necessary to relearn how to act on stage. incorporating , though, the truth demanded by the cinema and thereby reducing the measure of theatricality (Emphasis mine.)"
