(the) Yesterday Machine (1963)
Strange movie which is something of a cult fave now, low budget film with many actors who never did anything before or after this, some only have 2 or 3 movie credits. The really bad acting and clumpy script, actually, make the film humorous and almost fun. Includes a bad guy, sciences experiments and a girl with a hard southern accent- even though her sister (who looks old enough to be her mother or even Grammy) , has no such drawl...which adds to the thigh slapping laughs.
