I just finished reading Alan Cumming's memoir Not My Father's Son and in addition to being a terrific read, it is full of instances of him breaking down in tears.  It focuses on his childhood beatings and mental abuse at the hands of his father, the repercussions in his adult life and his quest to find out more about the mysterious death of his maternal grandfather.  He seems to be a very emotional person and even confesses to enjoying crying while watching Sandra Bullock movies on planes.
