It's a Wonderful Life (1946)
Frank Capra did it once again with It's a Wonderful Life. This take on a Christmas-time film explores the role of an overworked father in 1919. James Stewart's character falls into a time-warped alternative dimension where he doesn't exist.
The goal is to showcase to the audience how important the people around you are, but also how you matter to them. The holidays are stressful for most people, but this film serves as a great reminder to take it easy and appreciate the life around you.
