Daniel Day Lewis: How Far Will He Go?

"You mean I have to die to discuss your insights on death?" - Bones, "Star Trek IV"

Daniel Day Lewis never left his wheelchair during the filming of "My Left Foot". He slept in an abandoned jail cell for "In The Name Of The Father" and lived on "The Crucible's" village set without running water or electricity and he fended for himself in the wilderness for six months, sleeping with a rifle, to prepare for "Last of the Mohicans." He trained 7 days a week for 3 years, sparring with professionals, to become "The Boxer." He memorably freaked Cameron Diaz to high heaven by insisting that everyone call him Bill (his character's name), not Daniel, on set of "Gangs of New York." 

So.....if two time Oscar winner Day Lewis were going to play, oh, I don't know, let's say.....Abraham Lincoln, how far do you think he'd go to prepare?
