Brett Lang, reporting for Variety:
The 60-year-old star, who has played presidents, writers, and gang leaders in a career that has spanned four decades, has one final film awaiting release, “Phantom Thread,” a drama set in the world of high fashion. It is scheduled to hit theaters on December 25, 2017 and reunites him with Paul Thomas Anderson, who directed Day-Lewis to a best actor Oscar in 2007’s “There Will Be Blood.” Day-Lewis intends to help promote the movie, according to a person familiar with his plans.
He did not give a reason for his retirement. In a statement, Day-Lewis’ spokeswoman, Leslee Dart, confirmed the news: “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.”
At least we get one more Day-Lewis/Anderson collaboration before one of the greatest actors of his generation calls it quits. I was very much a Daniel Day-Lewis agnostic until There Will Be Blood came out, but his performance as Daniel Plainview has burnt it's way into the deepest recesses of my mind.
You can't have a serious conversation about the best movies of this century without talking about There Will Be Blood, and the brilliance of Day-Lewis.
