💀 @willsmith In I, Robot (2004) the production team created a physical NS-5 robot head with individually motorized facial components so animators could study how light and shadow played across the character during expressions. This practical reference helped ensure Sonny’s digital face could convey subtle emotion without looking rubbery or artificial. The blend of physical modeling and performance-capture data guided the final animation to look more grounded in real-world mechanics. (source: 20
