Day-Lewis is of British-Irish descent and is a method actor, which means that he gets into the character he is playng, feeling the same emotions that the character would in the situations he plays. It is said that he stays in character for the entire duration of movie shoots. He is also one of the most selective actors and has only starred in five films since 1997!
In 1989 Day-Lewis starred as Hamlet for the National Theatre, but collapsed in the middle of the scene where Hamlet sees the ghost of his father. After sobbing, Day-Lewis left and refused to go back on stage. He had seen the ghost of his own late father and he has refused to perform onstage since.
