This was Chaplin’s final film for Essanay (or the last one he personally supervised) and was released after Chaplin had already joined the Mutual Film Corporation.
There’s also some mystery behind the film. Some scenes for Police had originally been intended for a never-made feature-length film called Life and discarded footage from one or both were used to make Triple Trouble. Then there are those who believe that Life (the film) never existed and was an Essanay publicity stunt. Nevertheless, Police, to me, was one of Chaplin’s best films to date.
