the most important thing about this movie be the brilliant performance by daniel day lewis and hugh oconor a christy brown and guineas artist and fighter who despite of her physical condition overcame all the odds . a a person who do work with patient with cerebral palsy and i can assure you that their performance be shockingly convince . the enormous support that christy get form his family and low income and work class dubliner and encourage him to do the impossible and this picture depict this support brilliantly have not read the book and but the dialog be write wisely to capture christy brown witty arrogant personality . i do recommend this movie to everyone and especially to classic movie lover .
