Alec Baldwin pleaded not guilty Wednesday after a grand jury indicted him on involuntary manslaughter charges over the 2021 shooting death of a cinematographer on the set of Rust, a western film he was producing and starring in.

The actor waived an arraignment, which was set to take place Thursday, in a court filing alongside his plea.

Baldwin was indicted earlier his month in Santa Fe, New Mexico, after a second set of prosecutors revived the case against him following the death of Halyna Hutchins on Oct. 21, 2021. The actor, who is also one of the producers of the film, was pointing a gun at Hutchins during a rehearsal on the New Mexico set when the firearm went off. The shot killed her and injured director Joel Souza.

Baldwin has maintained he did not pull the trigger and had been told the weapon was cold, meaning it should not have contained any live ammunition. He has said there were other crew members on set responsible for gun safety.
