"I woke up to the messages and read the news and I am in shock. I was so lucky to have had @halynahutchins as my [director of production] on Archenemy. She was an absolutely incredible talent and a great person," Manganiello wrote, alongside a black-and-white photo of the cinematographer operating a camera on set.
"She had such an eye and a visual style, she was the kind of cinematographer that you wanted to see succeed because you wanted to she what she could pull off next… and she was a fantastic person," he continued. "There was no amount of pressure she couldn’t handle. She was a great collaborator and an ally to anyone in front of her camera. Everyone who knew her was rooting for her."
Manganiello also expressed heartbreak over the nature of her death and the circumstances surrounding the accident.
"I can’t believe that this could happen in this day and age… gunfire from a prop gun could kill a crew member? This is a horrible tragedy. My heart goes out to her family and especially to her son. I am so sad today for everyone who knew her and worked with her…" he wrote.
Additionally, Paul Scheer, who also worked on Archenemy, paid tribute to Hutchins on his Instagram Story.
Hutchins was fatally shot on the set of Rust after actor Alec Baldwin discharged a prop gun during production. Director Joel Souza was also struck and injured in the incident.
While uncommon, accidental deaths have been caused by prop guns using blank cartridges on film sets in the past. Actor Jon-Erik Hexum died from an inadvertent self-inflicted head injury caused by a blank on the set of the TV show Cover Up on Oct. 12, 1984.
Brandon Lee, the son of screen legend Bruce Lee, also died after being shot with in improperly made blank round during the filming of The Crow on March 31, 1993.
On Thursday, Lee's sister, Shannon Lee, tweeted her condolences and expressed her heartache over the tragedy.
"Our hearts go out to the family of Halyna Hutchins and to Joel Souza and all involved in the incident on Rust," she wrote. "No one should ever be killed by a gun on a film set. Period. 💔"
