Bat Pussy

Nothing is known about this porn movie. It is probably from the 70s, but we do not know the name of the director and not even the real name of the actors. It is one of the first porn parodies of the history of hardcore cinema. And it is also considered one of the ugliest porn movies of all time.
The intent is pretty clear: make a parody of the Batman TV series of the sixties.
There are no production credits and no one knew this film. It was discovered by chance in the 90s, when they found some boxes full of old tapes in the back of a porn cinema in Memphis.
The acting is embarrassing and the production level too. It is even possible to hear the director give instructions to the actors. You even hear an operator who burps during a sex scene!
