It doesn’t take much to give in and enjoy Ben Lewin’s fascinating “The Sessions”. Based on the true story of California based poet and writer Mark O’Brien, the film deals with O’Brien’s struggle with Polio and being forced to use an iron lung the rest of his life. It’s not as grim a subject matter as you may think. O’Brien is played by John Hawkes, a man we will certainly see at next year’s Oscar ceremony, in a performance that may recall Daniel Day Lewis’ in My Left Foot but with more humor and playfulness. Having learned to twist his body, learn to breathe carefully and use a mouth stick to dial a phone and type, Hawkes gets all the mannerisms right and makes us believe that he truly is in this sort of state. It’s no easy feat to act in a lying down position with an iron lung for an entire movie but if done well, this sort of showy performance usually spells awards for you.
