Talking Head (1992)

A revered director with an obscure style, Rei Maruwa, has gone missing during the production of his latest animated feature, Talking Head. With the deadline approaching and next to no progress made, the producer calls in a "shadow director" with the ability to mimic any director's style. Arriving at the studio, he begins meeting with the eccentric crew members in order to understand the project, but soon they begin dying in the same order that he met up with them.
