Muertos de risa (1957)

Funny little comedy about the impersonation of Doña Rosita (Resortes), a rich old lady whose heirs want to kill her, by Beto (Resortes), a carnival worker who is her dead ringer. The man is recruited by the Chief of Police to spend a weekend in her house, while several relatives try different methods to get rid of her. People fall from balconies, get poisoned, sit by a bomb that explodes, get scared by spiders, bats and big cats, but nobody dies or gets hurt. It's just silly "white humor", with a couple of musical numbers by María Victoria. The movie has nothing to do with horror, and it is not as wild as other movies with Resortes (who was a great dancer), but you can have a good time, with 76 minutes of light comedy played by an enthusiastic cast.
