Caught this movie way back in the 60's on Supernatural Theater. The movie The Blob Starring Steve McQueen was made one year earlier to American audiences. The success of the film despite the poor screenplay and acting gave Italian film makers an idea, a spin off.This movie was filmed in Black and white with poor dubbing. A group of archaeologists stumble across a cave laden with gold with the Mayan Goddess Caltiki. They find skeletons near the gold but fail to realize that a blob like substance is in the adjacent pool. Greed gets the better of our explorers as the first diver is consumed and the second diver Max (Gerald Haerter) barely escapes but has his arm consumed by the blob. Then you see the mass rise up from the pool ready to digest anyone in it's path. The crew barely escapes as the mass follows them out of the cave . Luckily a gasoline truck crashes into the mass/blob and destroys it. Next the team returns to Mexico City as their injured colleague is tended to to remove the blob scraps from his arm. Dr John Fielding (John Merivale) takes the blob substance and puts in his mansion for further analysis. Ironically a comet that passes the Earth every 850 years causes the blob to grow. Reminds me of the George Romero narrative in the Night Of the Living Dead. The Good Dr. Fielding tries to convince the Mexican government to destroy the blob but they arrest him instead. Meanwhile Dr. Fielding's house is being consumed with his lovely Wife and Daughter inside. I just enjoyed the ride from start to finish . Till this day foreign film buffs wonder who handled the bulk of the direction in the film. Was it Ricardo Freda or Mario Bava? I enjoyed this picture much more than the Blob despite it's many flaws especially in the special effects department. At times the mass looked like heavily stained bed sheets being pulled too and fro. The English voices were very distinguished, especially Max's character deep and throaty in nature. Just another 50's spaghetti sci-fi production that will leave you full.
