Baldwin made the plea while exercising his right to waive a first court appearance that was set for Friday, according to a court filing.

New Mexico First Judicial district attorney Mary Carmack-Altwies in January charged Baldwin and the movie’s set armourer, Hannah Gutierrez-Reed, with two counts of involuntary manslaughter for the 2021 death of cinematographer Halyna Hutchins.

Prosecutors last week downgraded charges against Gutierrez-Reed and Baldwin, reducing the possible prison time for the actor who fired a live round during a rehearsal, killing Hutchins and wounding director Joel Souza.

Baldwin’s defence team argued that he had been charged retroactively with a New Mexico firearms law that was passed after the shooting took place on Oct 21, 2021.

Gutierrez-Reed will make a first court appearance on Friday via video link, her lawyer Jason Bowles said.

First assistant director Dave Halls also plead not guilty in a Thursday court filing in which he waived a Feb. 24 first court appearance.

Baldwin and Gutierrez-Reed now faces a maximum of 18 months in prison if convicted. Before the prosecutor dropped the alternative charge he risked a minimum five-years in jail.
