Alec Baldwin has spoken for the first time about the incident which led to the death of a cinematographer and said he does not feel guilt.

The actor, 63, accidentally shot and killed cinematographer Halyna Hutchins, 42, and injured director Joel Souza, 48, when a prop gun he was holding went off during filming for the Western in New Mexico.

In his first interview since her death in October, Baldwin told Good Morning America host George Stephanopoulos he dreams about the incident “constantly”, but doesn’t believe that he was responsible.

In the exclusive interview, which aired on ABC in the US on Thursday night, Baldwin was asked if he felt guilt over Hutchin’s death, to which he replied “no” twice.

Adding: “I might have killed myself if I thought I was responsible, and I don’t say that lightly,

“I don’t know what happened on that set. Someone put a live bullet in a gun, a bullet that wasn’t even supposed to be on the property.

“Someone is ​responsible for what happened, and I can’t say who that is, but I know it’s not me.”

He said that he and Hutchins ‘had something profound in common, and that is we both assumed the gun was empty’.

Recalling the day of the shooting, Baldwin told Stephanopoulos that he and Hutchins had met to rehearse a scene in which he was playing a character who drew his weapon on two foes.

He said that during the rehearsal, the film’s first assistant director, Dave Halls, handed him a revolver and told him “this is a cold gun” – an industry term for a weapon that is either empty or loaded with dummy rounds.

The actor said Hutchins proceeded to instruct him on where and how to hold the weapon, ‘which ended up being aimed right below her armpit’.

In order to get a particular shot, Baldwin said he needed to cock the gun but not fire it.

He said: “I cock the gun. I go, ‘Can you see that? Can you see that? Can you see that?’. And then I let go of the hammer of the gun, and the gun goes off. I let go of the hammer of the gun, the gun goes off.”

Stephanopoulos then asked if Baldwin ever pulled the trigger.

Baldwin said that he cocked the gun but ‘didn’t pull the trigger’.

“No, no, no, no, no. I would never point a gun at anyone and pull a trigger at them.”

Amid speculation that Baldwin could face criminal charges over the incident, he told Stephanopolous that people ‘in the know’ thought it ‘highly unlikely’.

However, he said the events of the day continue to weigh on him.

“I go through my day, and I make it through the day. Then I collapse at the end of the day. Emotionally, I collapse.

“I couldn’t give a s**t about my career anymore.”

Stephanopoulos asks Baldwin ‘is it over?’, to which he replies: “It could be.”
