Peter Sarsgaard has defined what it is to be a character actor in this modern era. He possesses that rare and sought after ability to portray a villainous and hateful character but allowing the audience to not feel a sense of guilt to love that character, drawing out the innocence and vulnerability of a character without losing his strength.
Though he usually takes supporting roles, Sarsgaard has gained critics appraisal for his ability to draw you into the world of the character he is portraying. He almost captivates you with the quiet and calm way he loses himself in his character. He is one of the best, not only character actors, but actors of this modern era.
