Kevin Spacey. A man who is not limited by genre, by his range or by the roles and risks he is willing to take. He has always excelled as a character actor rather than a traditional leading man, and it is that skill and dedication to his craft that has led to him being the go to man for intricate roles in Hollywood. He is notorious for keeping his private life extremely private, and guarding every tiny detail about his himself outside of his characters with a fierce pride. He has been quoted as saying, 'the less you know about me, the easier it is to convince you that I am that character on screen. It allows an audience to come into a movie theatre and believe I am that person.' It is an admirable approach to acting and a fantastic example of the care he regularly displays for an audience and their experience in the cinema. That's a lesson a lot of big name actors could learn, because in the end, they are here to entertain us and us alone, not suits at a corporation. With that damning indictment of the film industry, let's take a look at 5 of Kevin Spacey's best performances, and 5 of his worst, all in celebration for the release of Horrible Bosses 2.
