Towards the end of The Last Jedi, we meet on Crait a number of Vulptex creatures, fox-like animals with crystalline bristles. Although a detailed animatronic was made for the production, the Vulptices were ultimately crafted in CG by ILM.
Academy Award nominee Ben Morris from ILM was the overall visual effects supervisor on The Last Jedi. The other VFX Oscar nominees for the film are Mike Mulholland, Neal Scanlan and Chris Corbould. Here, Morris explains the design of the Vulptices, and how they went through both practical and digital builds.
