Producers responsible for creating the movie "Rust," which was being filmed in New Mexico before an on-set shooting death resulted in its cancellation, are pushing back on claims that they knew firearm safety was a concern before the film’s cinematographer, Halyna Hutchins, was killed by a gun actor Alec Baldwin was holding. Rust Movie Productions LLC filed a notice of contest on Tuesday arguing that the findings by the New Mexico Environmental Department’s Occupational Health and Safety Bureau (NMED) – which last month fined the company $136,793 for its "willful and serious" violation of workplace safety procedures – have no clue what it’s talking about in connection to a fire extinguisher that NMED said was not properly inspected and maintained.
