"It is with heartbreak" that executive producers "have decided to cease all future production on the series."
"Safety is always of paramount concern. We maintained the highest safety standards throughout production, higher in fact than any protocols existing," the executive producers said, adding that the show had "many fewer incidents than occur" normally. "While we maintained the highest safety standards possible, accidents unfortunately happen, and it is impossible to guarantee they won’t in the future. Accordingly, we have reached this difficult decision."
