Another crew member who was working on the film Rust is in hospital, where doctors are fighting to save his arm following a spider bite.
According to a Just Giving page, Mr Miller was on the site of the Rust production in New Mexico when he was bitten by a brown recluse spider – a venomous spider that is native to North America.
Within days, he experienced severe symptoms including necrosis of his arm and sepsis.
The fundraising page says: "He has been hospitalized and endured multiple surgeries each day as doctors do their best to stop the infection and try to save his arm from amputation.
"It will be a very long road to recovery for Jason if the medical team is able to save his arm.
"If under worse circumstances he loses his arm, this is a life-changing and devastating event for Jason and his family."
