Sadly this is nothing new. While not exactly in the same league, it reminds me of when they were shooting the fourth Friday the 13th movie, back in 1984. There's a scene where one of the hapless teenagers goes skinny dipping in the lake. This scene was shot in the middle of fall, and that lake was ice cold. The poor girl was shivering uncontrollably, lips blue, yet director Joseph Zito heartlessly ordered her back in the water to finish the shot. Turns out her saving grace was the man behind the hockey mask, Ted White, who told Zito if she didn't get a chance to warm up he was walking off the set. Obviously you can't make a Jason movie without Jason, so Zito relented, but White was so disgusted with the entire affair he made sure his name didn't appear anywhere in the credits.
