It's a real moment," says John Mathieson, who filmed the crucial exchange between Hugh Jackman and Dafne Keen differently from any other part of the movie. It just might be the most emotional scene ever filmed for a superhero movie. After 17 years, Hugh Jackman's Wolverine delivered his final moments onscreen in a death that was well-earned and picture-perfect. As he's dying, Logan shares final advice with his daughter, Laura (Dafne Keen), telling her not to become what the scientists made her for. Laura calls him Daddy, and they both cry (and so did many moviegoers over the weekend). Oscar-nominated cinematographer John Mathieson broke with director James Mangold's preferred method of using just one camera at a time, because he felt it was essential to use two — one trained on Jackman, the other on Keen — to capture the very real moment unfolding between the two actors and to save them from having to perform the incredibly difficult scene over and over. In a conversation with Heat Vision, Mathieson also gives a closer look at Professor X's (Patrick Stewart) burial, that memorable casino hotel scene and the hidden tribute to Prince he put in the film.
