I watched the Universal-International 1954 3D monster horror film Creature of the Black Lagoon. It was directed by Jack Arnold and produced by William Alland (This Island Earth, It came From Outer Space, Tarantula!, The Deadly Mantis, The Mole People, The Colossus of New York, The Space Children, and the three Creature from the Black Lagoon films). The geology expedition ends up in the Black Lagoon off a tributary of the Amazon. Here they find more than just rocks.
