THE SNAKE PEOPLE or Isle of the Snake People was one of four films Karloff signed to make for Producer Luis Vergara. The Mexican filmmaker had obtained financing from Columbia Pictures to film them in Mexico. But due to the actor's emphysema and arthritis problems with his legs in a brace problems in high altitudes, the Mexican actors and crew came to Hollywood and shot the four films back-to-back in the Hollywood Stage Studios in Los Angeles instead. There, all of Karloff's scenes were filmed in five weeks during the Spring of 1968. During the filming, Karloff was physically incapacitated by lung trouble, which necessitated an oxygen mask from time to time. After Karloff's scenes were completed, the crew returned to Mexico and shot the remaining scenes there.
