Mr. Gleeson is always a very real and naturalistic presence onscreen. In the film “In Bruges,” the weight of the world in combination with his own past allows Mr. Gleeson to impart with every cell in his body an acting performance that makes you feel every step, breath and word he delivers. Using his girth like Sisyphus and his eternal struggle with the eternal question, “Is life worth living?” Mr. Gleeson’s character does everything in his power to somehow justify his profoundly troubled existence. But, alas, he tragically reaches his dark limitations and finds a flicker of humanity, thereby guaranteeing his doom. Such an actor is a gift to other actors by his very example of raw and refined talent that any artist can and should admire and be inspired by.
