Everyone knows that Day Lewis broke a couple of ribs playing the part of paralyzed artist Christy Brown in My Left Foot, and that he spent time in a prison cell to get into character of wrongly convicted Gerry Conlon for In The Name Of The Father.

Can you imagine the looks on the faces of every New Yorker he breezed past looking like an idiot? That’s dedication to your art, and no mistake.
