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)
