The first scene which Hauer filmed was his death scene, in which he was injured twice. A squib meant to simulate a gunshot exploded on the wrong side, severely burning him; a cable which yanked him (simulating the force of being shot) was pulled too hard, straining his back. Hauer later learned that the cable was pulled forcefully according to Stallone's order, and their relationship was then marked by disagreements. Although stories about their on-set arguments are still told by fans of the film and the actors, Hauer has said in interviews that he did not take the disagreements personally and the greatest problem during filming was the film's difficulty.
