Nobody expects a movie with a title like Hercules Against the Moon Men to be good, but it's not out of the question to hope it will at least be fun. Unfortunately, Moon Men is much too dull to be fun. Oh, you can laugh for a while at the silliness of its plot or the lack of discernible acting skill among most of its cast. You can while away a bit of time wondering whether its phoniness or the flimsiness of its sets that is more amusing. You can even try to decide whether the "alien" costumes might possibly have found their way onto a half-remembered Lost in Space episode. But soon the simply dullness of Moon Men will overtake the little fun you've managed to build up. Even the bad acting doesn't create the giggles it should -- aside from Delia D'Alberti's evil queen, most of the acting is simply flat rather than amusing. As the titular hero (which, in Italy, was actually a different character by the name of Machiste rather than the retitled-for-America Hercules -- so much for depth of character), Sergio Ciani (a.k.a. Alan Steel) ambles his way through the film expressing much more dramatic depth by flexing his arm muscles than by any muscles on his face. The direction is lifeless, the script is ridiculous, and there's a sandstorm sequence that seems to last an eternity. Diehard fans of this action film subgenre are really the only audience for this entry.
