Which unit does the 2nd assistant director work under?

The 2nd assistant director primarily works under the director's unit. This role is integral to managing the daily operations on set and ensuring that the director's vision is realized efficiently. The 2nd assistant director often handles the scheduling, facilitates communication between various departments, and assists the 1st assistant director in managing the cast and crew. By working closely with the director, the 2nd assistant director helps to keep the production on schedule and running smoothly, making their role pivotal within the director's team.

The other options, while important in the filmmaking process, do not accurately reflect the specific organizational structure that the 2nd assistant director operates within. The production unit is broader and encompasses various roles, including those outside the creative vision set by the director. The producer’s unit focuses more on the financial and logistical aspects, while the art department deals with the visual elements of the film, rendering them less relevant to the directorial support needed from the 2nd assistant director.
