Alec Baldwin has said he did not pull the trigger of the gun he was holding that killed a cinematographer on the movie set of “Rust.” In his first major interview since the tragedy in October, the US actor also said he has “no idea” how a live round had gotten onto the set of the low-budget Western in New Mexico. “The trigger wasn’t pulled — I didn’t pull the trigger,” he said in an excerpt of an interview with ABC News released on Wednesday. “No, no, no. I would never point a gun at anyone and pull the trigger at them. Never.” In the interview, set to air in full on ABC on Thursday evening, Baldwin did not elaborate on how the weapon had gone off. Baldwin, also a producer on “Rust,” was rehearsing a scene in which his character brandishes a Colt .45 when cinematographer Halyna Hutchins was shot and killed.
