"Rust" actor Jensen Ackles paid tribute to late cinematographer Halyna Hutchins in an Instagram post after she was killed in an on-set incident last week.

"This has been a tragedy of epic proportions that we are all still processing," the "Supernatural" alum wrote on Instagram on Sunday in the wake of Hutchins' death.

In his tribute, Ackles recalled a moment from earlier last week when he "felt compelled to tell Halyna just how awesome I thought she was."

"I told her how incredible I thought her camera shots were," he wrote, "and just how exciting it was to watch her and her team work. Truly. She laughed and said thank you and gave me a hug. I'll forever be thankful we had that moment."

"She had a spunk and passion that infected the entire crew from the top down," he added.

"She was an inspiration," Ackles wrote. "She will be incredibly missed by all of us who knew and admired her."

Production on the film has since been halted as police investigate the fatal incident.
