Sure, it’s a ‘prop.’ …Suuuuuuuuuure.
Okay it is a prop – but that story is still what the Esoterrorists RPG would use as an example of a ‘veil-out:’ where you come up with a fake story to explain away a supernatural event. In this case: giant rats in the sewers! Nah, man, it’s just a movie prop.
Classic.
