This must be a comedy, right? The sound and voice dubbing is as righteous as a Kung fu, film from the 70s. Anyone that writes a serious critique of this film needs to chillax.
They made this film in 1966 with a budget of $19k, where most of the actors never progressed after this and rightfully so. The editing, the lighting, the plot, the writing, etc., was done at a high school film class level.
Overall, you need to endure this film, sit back, relax and have this as a notch on your film suffrage belt. We laughed at its attempt and you should too.
