The Monster is a 1925 American silent horror comedy film directed by Roland West, based on the stage play of the same name by Crane Wilbur, and starring Lon Chaney and comedian Johnny Arthur. The screenplay was written by Willard Mack and Albert Kenyon. It is remembered as an early prototype "old dark house" movie, as well as a precedent to a number of horror film subgenres such as mad scientists with imbecilic assistants, among others. A great shot of the mad doctor and his monstrous cronies can be seen on the Internet. Some sources list the film's release date as March 1925 while others say February.
