    "M3GAN": 19 Cool Facts About Making The Murderous Marionette Movie

    How did the deadly doll come to life behind the scenes?

    With her viral dance sweeping TikTok, it's easy to forget she's not actually a real life social media star. But just how did the team behind M3GAN make her seem so real?

    1. James Wan and Atomic Monster pitched the idea to Jason Blum.

    2. As you may expect, Chucky had an influence on M3GAN.

    3. The team deliberately tapped into the idea of "uncanny valley" to up the creep factor as much as possible.

    4. The team behind the movie wanted the doll to be as realistic as possible, so tried to rely as little as possible on CGI.

    5. Director Gerard Johnstone was a stickler for the smallest details, ensuring every shot was signed off right down to the absolute minutiae of M3G4N's movements.

    6. M3GAN is played by two actors.

    7. That desire to straddle the line between human and doll meant they needed an actor the size of a doll.

    8. There were multiple puppets used for various different aspects of M3GAN's movement.

    9. These puppets are more masterpiece than marionette.

    10. While the doll had to be as close to human as possible, the actor who provided M3GAN's body movements in some shots had to learn to move more robotically.

    11. In fact, the creepy all-fours run you see in the movie and trailer wasn't planned.

    Director Gerard Johnstone said Amie's mom had sent him a video of Amie running across their carpet on all-fours.

    Johnstone decided to add it into the film, because "it was so creepy and unexpected — it was like she was a jungle predator sizing up her prey."

    12. ...and nor was the now-viral dance sequence.

    Johnstone was so impressed with Amie's portrayal of the killer doll with no prior experience that he wanted to tap into the areas she was already skilled in. 

    He encouraged Amie to work with dance instructor Kylie Norris to create a dance that was "creepy, but also kind of distracting." The two delivered five or six soft choreography options for the scene, which Johnstone describes as "all very strange and not what I had in mind at all, but they were all kind of great and weird and disturbing."

    Once he was happy with the final sequence, he "snuck the moment into the film to see if anyone would say anything."

    With the dance now an absolutely iconic moment from the film, it seems Johnstone made the right call!

    13. It was also not going to be put in trailers originally.
