Daniel Day-Lewis has won three Oscars and starred in countless films such as My Left Foot, Gangs of New York, and, of course, There Will Be Blood...just to name a few.
The thing is, nobody seems to know why.
His spokeswoman, Leslee Dart said this in a statement:
"Daniel Day-Lewis will no longer be working as an actor. He is immensely grateful to all of his collaborators and audiences over the many years. This is a private decision and neither he nor his representatives will make any further comment on this subject."
