I've had an interest in them lately. Like usual, this will be random.
Thomas Edison was the first one to adapt Frankenstein onto film.
He made the movie in 1910, which is clearly before the 1931 film. It wasn't discovered until 60 years later though.
You can watch it here.
There's a 1972 film called Blacula about an African prince that got turned into a vampire by Dracula.
It was one of the highest grossing films of the year and was the first film to receive an award for Best Horror Film at the Saturn Awards. The film is also notable for featuring the first two gay male vampires in film history.
The slime dripping in alien's jaws in Alien is K-Y jelly.
It's never been explicitly stated that Kong is a gorilla. However, Godzilla has been confirmed to be a dinosaur in multiple movies.
People often seem to get this backwards but this the truth. The only times Kong was called a gorilla by other characters is when it was used as a metaphor. He's also been called a giant monkey.
Also, don't bring up who would win in a fight since I'm already writing a take about it (and the answer should be pretty obvious).
The opening sequence for Jaws took 3 days to film.
To achieve the jolting motions of the shark attacking the swimmer, a harness with cables was attached to actress Susan Backlinie’s legs and was pulled by crewmembers back and forth along the shoreline. Spielberg didn’t alert Backlinie as to when she would be “attacked,” so her terrified reaction is genuine.
Optimus Prime and the Predator have the same voice.
Peter Cullen, who is uncredited in Predator, provided the voice for both.
The upcoming remake of The Mummy will be part of a shared universe featuring Wolf Man, Frankenstein's monster, the Invisible Man, and more.
The series will be called Universal Monsters. It's starring Russel Crowe as Dr. Henry Jekyll, Javier Bardem as Frankenstein's monster, and Johnny Depp as The Invisible Man.
