His film The Cook was considered lost for several years. A surviving print was found and shown, for the first time in over 70 years, in Venice 1999. The surviving print was found in the attic of a former hospital in Norway. Apparently, the director of the hospital in the 1920s and 30s felt that laughter and comedy helped soothe mentally challenged patients and kept a collection of short films by Buster Keaton, Harold Lloyd and Charlie Chaplin on hand. None of the other short films found were considered lost.
