On Earth, everyone can hear you yawn.
12 January 2015 | by BA_HarrisonSee all my reviews

They've got some nerve calling this film Alien 2: although certain elements have clearly been inspired by Ridley Scott's 1979 sci-fi horror classic, the film as a whole couldn't be more different…

Want tense, claustrophobic, space-bound, futuristic action? Not a chance. Sulla Terra, the film's subtitle, translates as On Earth, meaning that the film takes place on (present day) Earth, and under its surface in an admittedly impressive looking cavern. Unfortunately, this means we get endless tedious footage of the characters wandering around the cave, the director so preoccupied by the wonderful rock formations that he forgets all about telling a coherent story, throwing in such random nonsense as a telepathic speleologist just for the hell of it.

Looking forward to seeing a cool alien creature? Sorry. This film's extraterrestrial starts off as a blue rock, turns into a red hand puppet in a moment that rips off Alien's chest-burster (although I admit that the face-burster scene is pretty cool), and finally becomes a mass of indistinguishable and very unconvincing tentacle thingies.

Expecting ground-breaking special effects? No dice. This is a low-budget Italian production, so all we get is some grainy stock footage for scenes involving a space mission returning to Earth, and some cheap gore. Thankfully, the latter is pretty juicy: the aforementioned face-burster sees the victim's eyeball pushed from its socket before the creature erupts; one of the cavers has his head chewed off, the severed noggin (complete with assorted giblets) falling onto the rocks below with a satisfying 'thud'; and another guy's head explodes to reveal thrashing tentacles.

What about a thrilling finalé? I don't think so! After a couple of encounters with the creature, the last pair of survivors emerge from the cave to discover that the planet is totally deserted, with the exception of the alien, which chases them around for a while, director Ciro Ippolito employing dreadful alien POV shots. Eventually, Ippolito becomes as bored with proceedings as his viewers undoubtedly are, abruptly ending his film with a caption warning the audience "You may be next!". It's a lousy way to wrap up a fairly dismal film which is barely worth enduring for the gore (and a bit of gratuitous topless nudity from star Belinda Mayne).
