A muddled, typically bad, campy Italian science fiction film which is nonetheless a must-see for seekers of the weird and delightful. This is a badly-edited, poorly-dubbed mess of a movie, with a non-existent budget and a story which lacks a decent beginning, middle or end. Yet despite all the flaws it may have (including scenes of astronauts floating in space without helmets!), it remains a largely entertaining space vehicle full of strange creatures and bizarre special effects work.
Once the action shifts from Earth to space the film becomes much more interesting as a whole and packs some seriously bizarre situations into the short running time. Okay, so there isn't too much action on view, but we do get scenes of rayguns turning people into flaming skeletons and the 'comedic' effects of anti-gravity on the unwitting human inhabitants of the spacecraft.
The presence of two Italian babes (Leonora Ruffo and Leontine May) also makes things easy on the eye, with the former flame-haired girl in a tight-fitting PVC miniskirt and the latter dressed in a fishnet costume (with appropriate frilly bits; remember the kids) for a substantial part of the running time. For the girls, there are plenty of male models to make up the masculine side of the cast, including the presence of peplum icon Kirk Morris (ATLAS AGAINST THE CZAR) in a tight-fitting full body PVC costume as an alien guard. Eagle-eyed viewers may notice harsh-faced peplum star Gordon Mitchell in a one-scene cameo as the alien 'Murdu', appearing on a monitor, no less! Incidental pleasures include a run-in with a planet full of apes (yet this is no PLANET OF THE APES) who run around waving bones like would-be Ronnie Corbetts; the hilarious heavy breathing that first alerts our scientists to the presence of "something" under the ground; the un-politically correct replacing of the robot slaves with some unwilling Chinese men; plus the hilariously mock-serious "dire warning" of the ending which warns of the consequences of nuclear war. Much like the character of Leontine May in this film, 2 + 5: MISSION HYDRA is a pretty but vacuous Italian gem.
