Actor Alec Baldwin told ABC News' George Stephanopoulos in an exclusive interview that he had "no idea" how a live bullet got onto the set of his film, "Rust," but that he "didn't pull the trigger" on the firearm that killed one person and wounded another.

"I would never point a gun at anyone and pull the trigger at them, never," Baldwin told Stephanopoulos in a first look at the upcoming interview, which is produced by George Stephanopoulos Productions. It will air Thursday at 8 p.m. ET on ABC and will begin streaming on Hulu later that evening.

"Someone put a live bullet in a gun, a bullet that wasn't even supposed to be on the property," he added.
