Oh man, that sucks
We love seeing these movies with the explosions and gunfire and death defying drops, but the reality is for most everything we see, there is a guy literally putting his life on the line for that shot.
I asked a friend about this yesterday since he knows some of the people on the crew. What it was is a small boat getting its side blown out with stunt performers inside the boat. The way he worded it is it involved a smaller rubber landing boat as special forces would use and then he mentioned the metal boat so it sort of confused me. The explosion im told was done to blow the side of the metal boat out but it was too much and literally blew one guy up with the other guy nearly meeting the same fate. It was an accident, not pressured from anyone to perform as far as anyone is talking.
