This movie sounds very similar to Monty Python’s The Life of Brian. The major difference, aside from being about a Moses parallel instead of a Jesus parallel, seems to be that Herschel has been deluded into believing he is God’s prophet while Brian spends the whole movie begging the crowds to stop trying to make him their messiah. Apparently it was also protested by Jewish groups for mocking their religion. I didn’t find Life of Brian as blasphemous as everyone said, so I’ll reserve judgment here.
Yes, there was a remake in 2000, which I haven’t seen either, but I was aware of at the time (I was only 12, there was no way I’d have gotten permission even if I wanted to see it).
I’m surprised by the critics’ comments about the intelligence of the movie. There’s a similar poster out there that has the quote shown here as well as another one calling it “an intellectual’s Hellzapoppin“. Considering it’s impossible to find a poster that doesn’t sell the movie on Raquel Welch’s body, I never thought “smart” would be a word to describe it.
What really sold me on it was the lead duo of Peter Cook and Dudley Moore. I’m guessing the intelligence of the comedy comes from the ways the wishes get twisted.
