I watched the 1955 Universal International movie, Cult of the Cobra on Svengoolie. Six American Air Force officers are exploring an Asian Bazaar before shipping home, post World War II. They meet a snake charmer and convince him to sneak them into a secret ritual of Lamians (worshipers of women who can change into serpents). During the ceremony, they are exposed and the high priest pronounces a death curse on them. The movie is directed by Francis D. Lyon (The Great Locomotive Chase, Destination Inner Space, Castle of Evil, The Girl Who Knew Too Much)
I watched the 1958 Universal International black and white motion picture The Thing That Couldn’t Die on Svengoolie. Jessica has the power to use her divining forked stick to find water, and other items like a watch or wedding ring. This time she finds a buried copper chest, with writing in it, and she knows it is evil and should not be opened. The ranch hand gets the slow witted handyman to break into the box, before an archeologist can get there to examine it, where he finds a disembodied head that telepathically controls his mind.
