Self Actually is about Anthony, who is part of a scientific experiment. He is incarcerated in a room with somebody who appears physically very different, but in all other ways identical to him; one is the original, the other a clone. On a table in the middle of the room is a red button. The button will terminate the existence of the clone and free the original. Although they both have apparent absolute confidence they are the original, they harbour a tiny doubt. Their dilemma, which is the clone?
