A report into Alec Baldwin's fatal shooting of Halyna Hutchins on the set of Rust has found management "knew that firearm safety procedures were not being followed".
New Mexico workplace safety regulators have issued the maximum fine against the film production company.
They said it "demonstrated plain indifference to employee safety" and imposed a $139,793 (£107,019) penalty.
"Our investigation found that this tragic incident never would have happened if Rust Movie Productions, LLC had followed national film industry standards for firearm safety," said Environment Cabinet Secretary James Kenney.
"This is a complete failure of the employer to follow recognized national protocols that keep employees safe."

State authorities issue a "willful-serious" citation as they say established rules weren't followed on set and that Ms Hutchins' death could have been avoided.
