Creature from the Black Lagoon (1954)

Continuity mistake: When the scientists find the creature climbing onto the ship at one point, it's night time. It smashes a lamp, then jumps back in the water, swims across the lagoon, then standing up near the water's edge, it grunts and slashes at the spotlight they aim at it, then goes back underwater. Two of the scientists dive in to go after it, and follow it through an underwater (then above-water) cave. When both creature and scientists exit the cave, however, it is not only daytime, but the other scientists are waiting on the shore nearby.

Lucas: What kind of fishing is that? Who eats rocks?
Carl Maia: I eat rocks, in a manner of speaking. I crush and look inside them and they tell me things.
Lucas: What do they tell you?
Carl Maia: How old they are.

Trivia: William Alland who produced The Creature From The Black Lagoon, acted in Citizen Kane as the reporter who investigates Kane's career. During the filming Alland met Mexican cinematographer Gabriel Figueroa Mateos, who told him a legend of an amphibious creature who comes out of the River Amazon to seize women. Alland wrote a story based on the legend, which would form the basis of this 1954 horror film.
