Screened at Cinevent in 2019, Calling All doctors is a crowd-pleasing comedy about a hypochondriac and the precarious situation his condition puts him in. Charley Chase catches something from his sneezing secretary so he goes to his doctor. While standing in the waiting room, a man approaches him and tells him his doctor is busy and that since he is also a doctor and can treat him instead. Truly he is a mental case who believes he is a doctor. He convinces Charley to take him home with him, and makes him go right to bed; then he crawls in with him.
There are lots of laughs to be had from this one, both slapstick and sight gags. Charley has plasters on both his front and back, a barrel of aspirin in his room, and an atomizer that he accidentally fills with red ink. There are also bizarre twin paintings over his and his wife's beds depicting a woman who is overlaid onto a horse.
If you look closely you can tell that Charley's stunt double looked nothing like him.
