Tensions have flared on the set of teenage drama Riverdale after Kiwi actor KJ Apa was involved in a car crash following a 14-hour work day.
Apa, who plays protagonist Archie, was driving home after midnight last week when he fell asleep behind the wheel.
The car crash has triggered a "firestorm of protest" on Riverdale's set, according to The Hollywood Reporter, with one person telling the trade magazine it was only a matter of time before someone was hurt.
"They're working these kids from morning until night," the source said. "Someone's going to die."
There were reports Apa had worked a 16-hour day immediately prior to the crash, but Warner Bros has since issued a statement refuting those reports.
"We have a large cast of series regulars, and our actors do not work every day," the statement said. "On the day of the accident, KJ worked 14.2 hours. The previous day he worked 2.5 hours, and the day before that he worked 7.7 hours. KJ has repeatedly been informed about making production aware if he is tired or feels unsafe, and if so, either a ride or hotel room will be provided for him."
Warner Bros has also said reports of Apa being taken to hospital are untrue.
"He was treated by first responders on the scene and released by them," the statement said. "We also sent a doctor to his home later that same day for a follow-up to confirm his wellbeing."
The Screen Actors Guild has described the incident as "extremely troubling" and confirmed it is sending a team to Vancouver to review any safety issues that might be affecting cast and crew. Riverdale is currenty filming its second season outside Vancouver, Canada.
In July, a veteran stuntman was killed after a tragic accident on the set of The Walking Dead's eighth season. Just last month a female stunt driver was killed while filming a motorcycle scene for Deadpool 2.
