Day-Lewis, who grew up in London, is the son of actress Jill Balcon and the Anglo-Irish Poet Laureate, Cecil Day-Lewis. He is a method actor, known for his constant devotion to and research of his roles. Often, he will remain completely in character for the duration of the shooting schedule of his films, even to the point of adversely affecting his health. He is known as one of the most selective actors in the film industry, having starred in only five films since 1997, with as many as five years between roles.

His father had lived mainly in England from the age of two and later became the United Kingdom's Poet Laureate. His mother's family was Jewish and originated in the Baltics. His maternal grandfather, Sir Michael Balcon, was the head of Ealing Studios. Two years after his birth, the family moved to Croom's Hill, Greenwich, where Day-Lewis grew up along with his older sister, Tamasin Day-Lewis, who became a documentary filmmaker and television chef.
