“Obviously, the Orcs made some behind-the-scenes improvements to the new series. You go back 20 years and we used a foam rubber that’s basically, like a porous, porous rubber material. with a smooth or any textured surface,” Wilson said, describing orc design elements from Jackson’s movies. The design was “fantastic for the time,” but near the end of production, a new form of silicone prosthetic emerged that made the process much easier for Gimli actor John Rhys-Davies toward the end of the film.
The prosthetic manager says the ears, nose and other types of parts in “The Rings of Power” are made of “encapsulated silicone”, which is much more movable than previous materials. “It’s the same temperature as their skin,” Wilson explained to IGN. “And you can see the translucency and then you gently paint it on, like makeup on a person.” Compared to the old version, the old version is more like painting layers on rubber.
According to Galadriel actor Morfydd Clark, the film’s intensive realistic effects are one of the most surprising behind-the-scenes elements. She tell Collider that the cast is “really lucky that the orcs are all realistic”, though it’s unlikely she’ll be swapping places with the Orc actors, who have earlier call times than the others. “Also, the surprise is that it means you’ll be there at 7:00 a.m. like ‘God, it’s early,’ and the orcs have been there since midnight wearing prosthetics,” said Clark.
