Daniel Day Lewis in My Left Foot
This was the role that gained Daniel Day Lewis his reputation, and for a good reason – he did everything he could to perfect this role and really get into character. To help maintain the hunched position of his sick character, the actor reportedly broke his two ribs.
The actor refused to leave the wheelchair between takes and functioned as a handicap in his real life – he required help for eating and dressing, just like his character.
