I find it hard to take Jean Dujardin seriously after watching Lucky Luke, OSS 117 and Brice de Nice. I was amazed to know that he won the Academy Awards for Best Actor. I know he is a wonderful actor, but everytime I see him on screen, he is always funny; that it sounds like a joke that he won the Best Actor award :-) since usually the awards go to serious drama actors.
I think it's rather unbelievable that George Valentin's fans desert him that soon. I get an impression that he is a warranty for box office in the beginning of the movie. People come to the theatre to see him. When talking movies era begins, his movie producer replaces him with new faces; and since then only a few people come to the theatre to watch a movie he stars, produced and directed. Charlie Chaplin still made a silent movie in 1931 (City Lights) and it was a success.
