A couple more videos with information about the transformation scene –
Tanya Cornelisse, who plays Starla (the woman who turns into a goat) has a demo reel of several of her films. 3:05-3:50 is from the beginning of the ‘Yellow’ dinner scene – there’s no TF content shown, just the family members arguing in the lead-up to it, but it appears to be finished footage.
E.G. Daily, the woman who turns into a donkey, is briefly interviewed by one of her cast mates on the last day of shooting the dinner scene, in which she describes the animal makeup as taking ‘two and a half hours’ to apply. Again, there’s no TF content in this video, but she implies that the scene took several days to film (“and then we have to shoot our farm animal scene again”).
