It’s a Wonderful Life (1946)
Stars: James Stewart, Donna Reed
This undisputed classic is the absolute pinnacle of Christmastime movie joy for many, even though it isn’t actually a dedicated Christmas film. In actual fact it’s quite dark – George Bailey (Stewart) is at the point of suicide on Christmas Eve. An angel is despatched to save him, and we then witness many of the selfless things that Bailey has done for others over the years. Will he earn his wings and have a happy Christmas? If you don’t know the answer to that question, then please do treat yourself.
