Los Angeles, California - The assistant director of Rust is echoing Alec Baldwin's claims that he did not pull the trigger of the gun that killed cinematographer Halyna Hutchins on set of the movie.

Baldwin, who was holding the firearm that killed Hutchins and injured director Joel Souza on October 21, recently spoke with George Stephanopoulos for an hour-long special that will air Thursday at 8 PM on ABC.

"The trigger wasn’t pulled. I didn’t pull the trigger. No, no, no, no, no," Baldwin said in Wednesday's promo for the interview. "I would never point a gun at anyone and pull the trigger at them."

Now, ABC is citing assistant director Dave Halls' attorney, Lisa Torraco, who says his client gave him the same story. "Dave has told me since the very first day I met him that Alec did not pull that trigger," she told Good Morning America. "His finger was never in the trigger guard."

Torraco also confirmed that Halls was present when the gun went off, killing Hutchins and also injuring director Joel Souza. Both Halls and Baldwin insist that the tragedy was a freak accident.

Of the interview with Alec Baldwin, George Stephanopoulos said: "I’ve done thousands of interviews in the last 20 years at ABC. This was the most intense I’ve ever experienced. So raw. As you can imagine, he’s devastated."

Addressing, but not answering, a question about whether he would work on another film involving firearms, Baldwin said, "I do know that an ongoing effort to limit the use of firearms on film sets is something I’m extremely interested in."

"But remember, something I think is important: How many bullets have been fired on films and TV shows in the last 75 years? This is America. How many bullets have gone off on movies and on TV sets. I don’t know, billions? In the last 75 years? Nearly all of them without incident."

He called the Rust shooting "a one-in-a-trillion episode," and also noted that Hutchins was his friend.

Before that, in a series of now-deleted tweets, Baldwin wrote: "I’m fully cooperating with the police investigation to address how this tragedy occurred and I am in touch with her husband, offering my support to him and his family.

"My heart is broken for her husband, their son, and all who knew and loved Halyna."
