It's a Wonderful Life (1946)

Directed by Frank Capra

A holiday favourite for generations... George Bailey has spent his entire life giving to the people of Bedford Falls. All that prevents rich skinflint Mr. Potter from taking over the entire town is George's modest building and loan company. But on Christmas Eve the business's $8,000 is lost and George's troubles begin.

More than any other American director’s movies of the mid-20th century, Capra’s films gave the impression of being of the people and for the people—the cinematic equivalent of the Constitution.
