This list contains movies where they are live action but somewhere in the film we see a scene of a stop motion monster that was blended with the film some how to portray a look as if the stop motion is interacting between the actors. Or a character points somewhere and when the camera moves you see the creature making you infer that the monster is really there interacting with the characters. Also I will not include any fully stop motion movies the creature has to be part of a live action film. By creature I mean a, alien, dinosaur, animal, mythological creature, skeleton, ect. I tried to get every single monster movie on this list.

If I missed any comment them down below and I will add them to the list.
