Yes, Jerry Lewis did a science fiction movie.
And it was a Jerry Lewis farce. The one thing I remember best (mainly because I was a kid) was Dick Shawn as the neighboring Russian cosmonaut.
Anita Ekberg didn’t exactly hurt when it came to holding my attention, either.
Premise: NASA and the Soviets race to get the first married couple on the moon. Connie Stevens reluctantly marries Jerry in the name of national pride and scientific advancement. And drinking pill-based vodka (Just add water.)
