Becca and Howie Corbett are a couple struggling to return to their everyday existence several months after the tragic loss of their 4-year-old son. Both have different ways of dealing with their grief and their choices are gradually pulling them apart. ‘Rabbit Hole’ is another fine film, based on the Pulitzer Prize winning play by David Lindsay-Abaire, from director John Cameron Mitchell. A sensitively performed and, at times, unexpectedly witty portrayal of a family in crisis.
