Kevin Costner played Garrison trying to find the truth in "Assassination of Kennedy", and his low-key acting style is very suitable for this movie. But before the film was filmed, after seeing the script sent to him by Oliver Stone, he turned down the invitation of the great director. You know, Mel Gibson and Harrison Ford were also invited. In the end, it was with the help of Kevin Costner's agent that he was persuaded to participate in the film. After accepting this role, Costner conducted a detailed study of Garrison's role. He visited Garrison himself and his friends, as well as his enemies.
