With Daniel in there it definitely should be amazing. That guy gets into character like no other.

The Boxer: Trained for 18 months with former world champion Barry Mcguigan who later said that Day Lewis could have easily been a professional afterward.

The Crucible: Etched actual tattoos onto his own body, "lived in the film set's replica village without electricity or running water" and built his character's house using 17th-century tools.

Gangs of New York: In preparation for his role as Bill the Butcher, Daniel Day Lewis actually took up an apprenticeship as a butcher; he would sharpen his knives during breaks in filming. He was also diagnosed with pneumonia on set, after continuously refusing to wear warmer modern coats as they 'wouldn't have existed in the 19th century'. Reportedly traipsed about picking fights with strangers during the filming.

My Left Foot: During filming as paralytic Christie Brown, Lewis refused to leave his wheelchair between scenes, so he could truly experience the problems associated with the condition. His constant refusal to break from character also earned him 2 broken ribs, from his continually hunched position in the wheelchair. He somehow sat still so hard that he broke his own ribs, and still didn't move.

Last of the Mohicans: Lived in the wild for 6 months, surviving only on necessities.

In the Name of the Father: For the part of a prisoner, Lewis lived in solitary confinement at an abandoned prison. He slept in an abandoned jail and ate only prison food.
