The New Janitor

The New Janitor was the 27th comedy from Keystone Studios to feature Charlie Chaplin. The film is arguably one of his best for the studio, and a precursor to a key Essanay Studios short, The Bank. The film also demonstrates the differences that Chaplin had with Keystone comedy in that it is a coherent whole in which the stock characters actually fill some emotional center. Chaplin brings a certain complexity to his janitor, unusual to the comedy factory of Mack Sennett. The film, which stars among Sennetts bit players Jess Dandy, Al St. John, John T. Dillon, and Helen Carruthers, is far more centered and clear in direction. Comedy flows from within the story rather than as a byproduct of story. After all this is a typical bank robbery storyline.
