PRAY, Mont.
— Alec Baldwin was mounted on a chestnut horse in a steep gully in a snow-dusted valley in Montana on Friday, his first day back filming “Rust,” the western whose cinematographer was shot and killed in 2021 when a gun he was practicing with on its set went off.
“Set, ready, and … action,” cried Gerard DiNardi, the movie’s new first assistant director, and Mr. Baldwin urged the horse forward, toward a camera rigged on a pickup truck.
As Mr. Baldwin returned to the set of “Rust,” prosecutors in New Mexico filed court papers formally dismissing, at least for now, the involuntary manslaughter charges he had been facing in the shooting of the film’s original cinematographer, Halyna Hutchins, who was killed outside Santa Fe, where the movie was initially filmed.
The prosecutors, Jason Lewis and Kari Morrissey, wrote in their filing in the case of the State of New Mexico vs. Alexander Rae Baldwin III that they were withdrawing the charges against him “since new facts were revealed that demand further investigation and forensic analysis” that could not be completed before a hearing, set to begin on May 3, at which a judge was to rule on whether the charges against Mr. Baldwin could proceed.
