Toothgnasher and Toothgrinder had their own team of makeup artists.
Jake Morrison, VFX Supervisor for Marvel Studios' Thor: Love and Thunder, shared how the goats Toothgnasher and Toothgrinder were made.
Toothgnasher and Toothgrinder are the mystical goats owned by Thor. Morrison starts by saying that no goats were harmed in the making of the movie. The goats were supposed to be the size of Clydesdale horses, which are enormous.
The team put a lot of effort into making the goats: the animals' hair was real and planted in by hand. The team also made realistic tongues for the models. Toothgnasher and Toothgrinder even had a whole team of makeup artists working only on them. Morrison said they'd run in with a glycerin spray and use it "just so the tongue was, like, extra wet for that kind of reference."
The Supervisor also shared his favorite "goat boat" moment:
"The best goat boat moment is the moment when Korg, finally, manages the whistle in the Golden Temple. You hear the scream of the goats. And the next thing you know, you're looking at the stained glass window, and the goat boat smashes through. It's classic goat boat."
