Gloria Allred, who is representing the sister and parents of Ms Hutchins in a civil trial seeking damages, made the comment after a criminal manslaughter case against the actor fell apart.

It comes as Baldwin shared his first comment since the case was dismissed on Friday.

"There are too many people who have supported me to thank just now," he wrote in a post on Instagram.

"To all of you, you will never know how much I appreciate your kindness toward my family," he added.

The involuntary manslaughter case against Baldwin over the fatal shooting of Ms Hutchins on the set of Rust was dismissed yesterday.

The award-winning actor, 66, broke down in tears and hugged lawyers following judge Mary Marlowe Sommer's decision.

She agreed with his lawyers that prosecutors and police withheld evidence about the source of the live ammunition that killed 42-year-old Ms Hutchins in 2021.

She threw out the case three days after the trial began in Santa Fe, New Mexico, and 18 months after charges were filed.

Speaking at a press conference on Saturday, Ms Allred said of Baldwin: "He should just have the human decency to say 'I'm sorry' in a phone call or Facetime to the parents.

"This was somebody's daughter, somebody's sister.

"It's not all about Alec Baldwin. There are victims in this case. They are not celebrities - they matter."

She described the decision to drop the case as "shocking, devastating", and a "punch in the gut", adding that it was "such a disappointment for Halyna's family" and would add to their "pain and suffering".

Baldwin had always denied the charge, maintaining he did not pull the gun's trigger and that others on the set of the Western film were responsible for safety checks on the weapon.

He faced up to 18 months in prison if he had been convicted.
