Following the bombshells of Quiet on Set, Investigation Discovery is back to shed light on the dark secrets behind more ’90s childhood favorites

In the third episode of its new docuseries Hollywood Demons, which premieres Monday from 9-11pm ET on ID and streams on Max, a writer and actor from Mighty Morphin Power Rangers (1993-’95) recalled the “abusive” on-set conditions that led to one background actor suffering heat stroke while filming the pilot.

“When we’re shooting the pilot, we’re out in the desert — it’s got to be 110 degrees — and someone has heat stroke,” said Audri Dubois, who originally played yellow ranger Trini, in an Entertainment Weekly preview. “It was one of the bad guys in a wet suit with a rubber mask over their head with pinholes for the eyes and mouth. He’s flopping around like a fish. … Me and the others had come together and agreed we were not going to continue shooting until this guy gets in an ambulance.”

Dubois’ role was recast with Thuy Trang before the pilot aired. Trang left the show in Season 2 over contract disputes.

Dubois continued, “It was offered to anyone there that they would get $100 if they took that man’s wetsuit off and put it on so that we could continue shooting, and someone did. The original then was in his underwear in the dirt, flopping around waiting for an ambulance.”

“I was watching that going, ‘What? This is not okay. It’s scaring me,” she said.

Head writer Tony Oliver explained, “Basically, these contacts made it okay to work you to death, and they did. They’re not just sitting around saying lines. They’re jumping around, it’s very physical. They have to work out and train to maintain their characters. Our shoot days were much longer, we shot 12- to 14-hour days where unions were eight to 10, so it could be a little abusive to the actors.”

Based on Kyōryū Sentai Zyuranger, an offshoot of the Japanese Super Sentai franchise, Mighty Morphin Power Rangers kicked off a massive American franchise of its own when the Saban Entertainment series debuted on Fox Kids in 1993. The Power Rangers have since appeared in four feature films and more than 25 tv series spin-offs.
