‘The Revenant’ was hard to watch for several reasons, but the worst part for Leonardo DiCaprio was actually the scene where he eats bison liver. DiCaprio willingly ate raw bison to keep with the authenticity of the film, despite being a vegetarian. Production even had to get permission from his lawyers and agents to give him the raw meat. He said the worst part was biting into the outer membrane, which bursts inside your mouth when you bite into it. Damn Leo, you deserved that Oscar.
