Marlon Brando had mixed feelings about acting and showed interest in new technologies that could reduce his on-screen workload. His affinity for visual effects and digital doubles is revealed in unpublished footage featured in the documentary "Listen to Me Marlon."

Brando partnered with Scott Billups, a cinematographer and graphics pioneer, to explore the "digital equivalence" technology. They experimented with creating a realistic digital double of Brando using an early version of a 3D scanner.

The process involved a 360-degree scan with Brando sitting still, which was a challenge given his restless nature.
