Paul Greengrass made the use of handheld camera 'hip' in Hollywood with his 'Bourne' movies and, by all accounts, he should most definitely be put on a list of the most influential action filmmakers of the 21st century. His films make you feel like you are really there, in the thick of the action. His very best work ("Captain Phillips," "United 93," "Blood Sunday," "The Bourne Supremacy"), heroic stories of unimaginable horror with edge of your seat thrills, reinforced the importance of the handheld camera, as a way to bring ultra-reality, at the movies.
