Here is a video of Semon in the 1925 film, The CloudHopper
Reading about Semon's demise is quite sad. The story surrounding his death, as recounted by his wife, is rather mysterious. The Wizard of Oz
was a financial disastor for Semon and he never really recovered. Some of his shorts are quite enjoyable. As Derek noted, he was never able to elevate his films to the level of the "Big Three." Still, there is much to enjoy in his films.
