This film was a lot of fun to watch--with some wonderful clips of Laurel and Hardy, Charlie Chase and others. What a lot of fun stuff! However, there is a BIG, BIG problem with the film. Nowhere in it do you see clips of Chaplin, Keaton or Lloyd--the three biggest film comedians of the 1920s. This is akin to a documentary about the 1960s without mentioning Vietnam or The Beatles! It's obvious that Robert Youngson just didn't have access to these other clips or he simply slapped them together without considering this. In his next film, WHEN COMEDY WAS KING, you DO get to see clips of Chaplin and Keaton--but, unbelievably, there is no Harold Lloyd! Well, if you JUST watch the film for its entertainment value, it's great. If you watch it for a historical overview, it is sadly incomplete and gives a false impression of the era.
