People familiar with ZOMBIE will recognize a humorous beginning, showing an empty vessel entering New York Harbor while a police officer remarks that its skipper "must be a real turkey." You’ll also quickly notice a significant amount of narration by Nick Alexander, who voiced one of the main characters in ZOMBIE. It's essentially an exploitation film capitalizing on another exploitation movie! However, things quickly decline once you experience some truly awful dialogue, substandard production values, and even worse editing as the story progresses. The initial portion of the film is somewhat salvaged by showcasing impressive exploding body effects, though the plot struggles to integrate them into a coherent and enjoyable narrative. Instead, the characters abruptly travel to South America—presumably because the producers wanted a getaway—and essentially do nothing! They get to observe a factory tour, and Louise Marleau participates in a shower scene that doesn’t reveal much. Eventually, they confront a motionless alien positioned at the end of a hallway reminiscent of the Italian-co-produced "Dragon's Domain" episode from SPACE 1999. Surprisingly, for sci fi director Cozzi, the film remains frustratingly Earthbound in this low-budget ALIEN imitation, and there are no cheap stop motion Harryhausen homages to be found. Instead, all the excitement derives from the kills, which vary considerably in quality. If the movie had embraced a more exploitative style with even more exploding bodies, it might be better remembered. As it stands, it’s hampered by a painfully slow pace that isn't helped by the ordinary dialogue and underdeveloped characters. A capable supporting cast including Ian McCulloch, Siegfried Rauch, and Marino Mase are mostly wasted, while star Marleau doesn’t seem very engaged. The only real positive aspect is a few of Simonetti’s synthesizer pieces, which effectively create an eerie and otherworldly atmosphere. I find the ending in New York to be particularly amusing, where some of the exploding toxic pods ended up in a random pile of trash on the sidewalk. One of them bursts in the final freeze-frame, but I'm sure that none of the local pedestrians, accustomed to the filthy state of the city during the 1970s and 80s, even registered it.
