"Hollywood: Hollywood Goes to War" is a fantastic episode from a wonderful series by David Gill and Kevin Brownlow. I loved it because it really did a great job describing how the American film industry came to surpass Europe's as well as showing the rather schizophrenic way the industry handled WWI--ranging from deploring the violence to heartily endorsing it!! This switch was amazing due to how quickly this occurred as well as showing one man (D.W. Griffith) who made the most Anti- and Pro- war films--one after the other!! Very well documented, fascinating and well worth your time. And, don't worry that the film ends with discussing the great American anti-war film "All Quiet on the Western Front". Yes, it WAS a sound film but because of when it was released, both sound AND silent versions were made as many theaters had yet to make the switch.
