                                                            2000s

After a five-year absence from filming, Day-Lewis returned to act in multiple Academy Award-nominated films such as Gangs of New York, a film directed by Martin Scorsese (with whom he had worked on The Age of Innocence) and produced by Harvey Weinstein. In his role as the villain gang leader "Bill the Butcher", he starred along with Leonardo DiCaprio, who played Bill's young protegé. He began his lengthy, self-disciplined process by taking lessons as an apprentice butcher, and while filming, he was never out of character between takes (including keeping his character's New York accent).At one point during filming, having been diagnosed with pneumonia, he refused to wear a warmer coat or to take treatment because it was not in keeping with the period; however, he was eventually persuaded to seek medical treatment.His performance in Gangs of New York earned him his third Academy Award nomination and won him the BAFTA Award for Best Actor.

After Gangs of New York, Day-Lewis's wife, director Rebecca Miller (daughter of playwright Arthur Miller), offered him the lead role in her film The Ballad of Jack and Rose, in which he played a dying man with regrets over how his life had evolved and over how he had raised his teenage daughter. During filming he arranged to live separately from his wife in order to achieve the "isolation" needed to focus on his own character's reality. The film received mixed reviews.

In 2007, Day-Lewis appeared in director Paul Thomas Anderson's loose adaptation of the Upton Sinclair novel Oil!, titled There Will Be Blood. Day-Lewis received the Academy Award for Best Actor, BAFTA Award for Best Actor in a Leading Role, Golden Globe Award for Best Actor - Motion Picture Drama, Screen Actors Guild Award for Outstanding Performance by a Male Actor in a Leading Role - Motion Picture (which he dedicated to Heath Ledger, saying that he was inspired by Ledger's acting and calling the actor's performance in Brokeback Mountain "unique, perfect"), and a variety of film critics circle awards for the role. In winning the Best Actor Oscar, Day-Lewis joined Marlon Brando and Jack Nicholson as the only Best Actor winners awarded an Oscar in two non-consecutive decades.

In 2009, Day-Lewis starred in Rob Marshall's musical adaptation Nine as film director Guido Contini. Day-Lewis was nominated for the Golden Globe Award for Best Actor - Motion Picture Musical or Comedy and the Satellite Award for Best Actor - Motion Picture Musical or Comedy for his role, as well as sharing nominations for the Screen Actors Guild Award for Outstanding Performance by a Cast in a Motion Picture and the Broadcast Film Critics Association Award for Best Cast and the Satellite Award for Best Cast – Motion Picture with the rest of the cast members.
