The Right-Minded Madman (1968)

Just where is the dividing line between sanity and insanity? Apparently, it doesn't take much to enter the unfathomable realm of lunacy--winning the lottery should do the job, especially when you are Labros Labretas, a humble white-collar worker oppressed by his mother-in-law. Fortunately, Labros' visit in the mental institution is a brief one; however, as the completely cured inmate returns home more sane and rich than ever, nothing can prepare him for the dramatic and utterly unpredictable changes that await. Now, it's the whole world, and above all, his nouveau riche family that have turned mad--but, what's even worse than that--is that some of Labros' money is missing. Can the freshly-released madman teach his own kindred a thing or two about life?
