1 of 14It's a Wonderful Life (1946)
One of the most popular holiday films of all time. This bracingly unsentimental celebration of family, friends and the power of one good man (James Stewart) to change many lives has been remade but never bettered. There's a reason for all the parodies, pastiches and homages -- it's so good everyone wants a piece of it.
