Highlights, well there are many. The Roman Empire and French Revolution segments are the longest and have the most gags including the Count de Monet who is always furious at people saying his name wrong, Nero at Caesar's Palace (actually the real Caesar's Palace in Las Vegas), Judas at the Last Supper and Moses dropping one of his stone tablets (so that's why there were ten rather than fifteen commandments)...
Although the film is listed as Part 1 there was no sequel. We do have a pseudo trailer for that film though to close things out, including Hitler on ice and Jews in space! A very silly film full of obvious visual gags and weirdness. A complete and utter laugh riot.
