Marvel Studios did not immediately respond to The Washington Post’s requests for comment. In a statement to several news outlets, a Marvel spokesperson said that “our thoughts and deepest condolences are with his family and friends, and our support is behind the investigation into the circumstances of this accident.”

“Wonder Man,” an upcoming Disney Plus miniseries whose production was halted by the Hollywood strikes last year, was not being filmed while the crew was working Tuesday, according to Deadline.

The show stars Yahya Abdul-Mateen II (“Aquaman,” “Watchmen”) as Simon Williams, an actor and stuntman who gained flight powers and superhuman strength to become the superhero Wonder Man.

The crew member’s union, the International Alliance of Theatrical Stage Employees, shared a statement on social media following Osorio’s death:

“Everyone in the IATSE family is shocked and deeply saddened by this tragic loss. We are working to support our member’s family and his fellow members and colleagues,” IATSE said. “Safety on set is our highest priority and we will assist [authorities] in their investigation in any way that we can.”

The California Department of Industrial Relations, in a division created through the California Occupational Safety and Health Act, is investigating the incident.

Lighting Technicians IATSE Local 728, Osorio’s local union, texted members about his death and said it was working with the Motion Picture & Television Fund to support Osorio’s family and fellow crew members.

“Remember that as much as we love what we do, the goal is always to go home safely at the end of the day. One of ours is not going to do that today,” the statement said. “Please keep their family and crew in your thoughts and prayers today, and respect their privacy at this time. Stay safe everyone.”
