The People That Time Forgot (1977)

Now if you thought the "Land That Time Forgot" was cheap and cheerful (and it sure was) then this one must have been done on a shoestring. It is a howler of a film with Patrick Wayne and Sarah Douglas on the hunt for a missing explorer (Doug McClure). They find him and together with a preposterously eccentric Thorley Walters try to escape from the evil Samurai-esque tribe (who seem to have their own, rather bizarre, theme music) who want to sacrifice them. Whereas the other three films in this "series" were fun and had a little panache, this just has bleak scenery and a plot that your average 5 year old could come up with.
