Alec Baldwin and other producers on the film Rust filed a motion to dismiss a lawsuit alleging that Baldwin’s actions on-set were a direct assault on one of the film’s employees.

The motion, filed in the Los Angeles County Superior Court on Monday, aims to dismiss a lawsuit filed by Rust’s script supervisor, Mamie Mitchell, who alleges that she “sustained serious physical trauma and shock and injury to her nervous system and person” due to being in close proximity to the shooting. The motion offers the first look at the legal defense that Baldwin may use to defend himself from culpability in the shooting that led to the death of cinematographer Halyna Hutchins.
