The 2-reel (20 minute) comedies Laurel & Hardy, Edgar Kennedy, Leon Errol, Charley Chase etc did were very good, just the perfect length, and should be shown today.
Also agree with the comments about Will Hay, he made his films in a relatively short space of time, during which he was as popular as any other comedian there was. Very under-rated and largely forgotton today.
A shame a lot of people mostly think of Chaplin as being the best; the younger generation should have the chance to view a lot of the others work to see what talent there was.
