"Way...Way Out" is an unusual Jerry Lewis film mostly because it isn't really a comedy. Sure, it has a few laughs here and there, but the overall effect is more like a commentary about the Cold War than a funny film. To put it bluntly, it isn't particularly funny--though it is interesting.
The film is set in the near future. There is an American and Russian base on the Moon and both are quite small--with two persons in each. As for the American base, the men aboard keep going crazy--presumably because they cannot function without women. But, the Russians have sent a man-woman team and their base is functioning much better. So, the head of the American space agency (an oddly cast Robert Morley) has determined that the next team going to the station will be married. The problem is that the next man scheduled to go (Jerry Lewis) is single and has no particular plans to marry. But, when told they want him to marry a pretty lady (Connie Stevens), he's in favor of the idea--but she isn't. So, the pair agree to go and to marry but not to consummate the marriage. The rest of the film is basically waiting until Stevens changes her mind. In between there is a pretty silly (and forgettable) plot involving the two Russians (Dick Shawn and Anita Ekberg).
The bottom line is that the film lacks laughs but is also inoffensive and an interesting look into the times in which it was made. A must for Lewis fans--otherwise, an inoffensive time-passer and nothing more.
By the way, I am not sure why but if you watch the veteran actor Sig Ruman closely, you can tell his voice is dubbed. Perhaps he had trouble doing the Russian accent credibly.
