20 TERRIBLE Horror Movies With INSANE Endings

Rats: Night of Terror delivers exactly what it promises on the tin - a B-movie about genetically mutated killer rats which terrorise the denizens of a post-apocalyptic world.

While it's ripe for some campy laughs courtesy of its atrocious English dub - it is an Italian production after all - and generally basement-low production values, it also would've probably been forgotten in short order if not for its completely deranged final scene.

At the very end, the remaining survivors are saved from the pursuing rats by a group of apparent humans in hazmat suits, only for one of them to remove their gas mask to reveal that they're actually a fleet of humanoid rats.

We and the movie's characters are given about 10 seconds to reflect on this insane revelation before the credits abruptly roll, ensuring no further elaboration is given.

In the very least, this ending ensured that nobody will ever quite fully forget about Rats: Night of Terror.
