The mouth burster was the first shot/effect we had as the creature department. And it was on location in Milford Sound in New Zealand at the beginning of principal photography. It was basically a big sack coming out of a mouth. And so for that particular scene we built a full animatronic puppet painted by Damian, a likeness puppet, we had prosthetics on the actor, and then the neomorph baby puppet itself. So that had everything going on. The location was this like, you know reeds and tidal water, it was at night, freezing, lots of insects eating you alive. There was so much blood, so much goo, so much chaos, four cameras and crew standing around us and four of us puppeteering this slippery little Neomorph.
