"I think it's important not to redefine somebody's motivations. (In a movie) you have to have people do or say things they never did or said, and be in places they never were. But you can take that to an extreme where it's not really why this person does what he does, and that's the key. You've got to be a journalist and a historian and a filmmaker all at the same time," Hanks told Parade magazine.
The biopic is based on the memoirs of Phillips, who was at the helm of the ship and was taken hostage by the pirates who fled the Maersk aboard one of the ship's lifeboats.
The film received a standing ovation when it opened the New York Film Festival and is touted as Hanks best performance in ten years.
