In a comedy atmosphere, this movie, follows the struggles of Cameron, a smart man with bipolar disorder, who makes his mind to win back the heart of his wife through caring for his two young daughters during her travel to New York.
Ruffalo is generally wonderful at finding the tone and mood of a character and holding to it; here he has to bounce about, but again he latches onto a consistent energy that makes Cameron a singular life force.
Writer/director Maya Forbes' autobiographical fingerprints are all over Infinitely Polar Bear, a disarmingly joyful recollection of being raised by her bipolar father in the 1970s...yet the film feels universal.
Cynics may scoff at the fact that Infinitely Polar Bear glosses some of the filmmaker's darker memories, but they'll need an ice bucket handy if they intend to avoid its warmth altogether.
