"Kubrick also found the ideas of Constantin Stanislavski to be essential to his understanding the basics of directing, and gave himself a crash course to learn his methods. He explained their significance:
'The equivalent to Pudovkin's book on film editing is a book oddly enough about Stanislavsky, not by him: Stanislavsky Directs, by Nikolai M. Gorchakov. It provides a very detailed and practical description of Stanislavsky at work on different productions. I would regard it as an essential book for any intending film director.'"
