The most recent tragedy on this list, Sylvester Stallones sequel cost $92,000,000 and one stuntman his life to complete. Kun Liu was performing stunts for a scene which placed him on an exploding boat when something went wrong and he was killed. His parents have started a lawsuit against Millennium Films, claiming that the stunts were not planned out well enough and that their son had not been trained to perform the stunt properly. Whether this is true or not, Lius death just goes to show us that, if you put yourself at risk, you cannot be surprised if something goes awry.
