The actor previously pleaded not guilty to two counts of involuntary manslaughter over the fatal shooting of Rust cinematographer Halyna Hutchins.

The DA said the motion, filed last month by Baldwin’s lawyers, was based on a ‘novel theory that has no support in New Mexico statutes or case law’.

The film set will ban the use of any working weapons or ammunition and include on-set safety supervisors.

Cinematographer Ms Hutchins died after a prop gun held by Baldwin was discharged.

The decision, made by Mary Carmack-Altwies and special prosecutor Andrea Reeb, will be shared via a written statement at 9am local time on Thursday.
