It's a Wonderful Life is an American Christmas drama film produced and directed by Frank Capra, that was based on the short story "The Greatest Gift", written by Philip Van Doren Stern.

Released in 1946, the film stars James Stewart as George Bailey, a man whose imminent suicide on Christmas Eve brings about the intervention of his guardian angel, Clarence Odbody (Henry Travers). Clarence shows George all the lives he has touched and how different life in his community would be had he never been born.

Despite initially being considered a box office flop due to high production costs and stiff competition at the time of its release, the film has come to be regarded as a classic and is a staple of Christmas television around the world. Theatrically, the film's break-even point was actually $6.3 million, approximately twice the production cost, a figure it never came close to achieving in its initial release. An appraisal in 2006 reported: "Although it was not the complete box-office failure that today everyone believes ... it was initially a major disappointment and confirmed, at least to the studios, that Capra was no longer capable of turning out the populist features that made his films the must-see, money-making events they once were."
