M3GAN is here to be "your new best friend," which is already concerning from the get-go. With horror dolls like Annabelle and Chucky dominating popular culture, M3GAN is another creepy toy joining their ranks. 

The upcoming spooky movie is directed by Housebound's Gerard Johnson, with Blumhouse's Jason Blum and Saw and Annabelle director James Wan serving as producers, so there are some big horror names attached to the project.

Fans are already hyped about M3GAN after the doll has gone viral on Twitter, with many people reposting clips of the doll dancing and generating a lot of buzz.

James Wan spoke to Empire (opens in new tab) about the movie where he described it as "Annabelle meets The Terminator." If that isn't enough to intrigue you, you can read even more below...
