Mary Treen was an American film and television actress. A minor actress for much of her career, she managed to secure a plain, unassuming niche for herself in dozens of movies and television shows in a Hollywood career spanning four decades, from 1930 to 1981.

It's a Wonderful Life is a 1946 American Christmas supernatural drama film produced and directed by Frank Capra. It is based on the short story and booklet "The Greatest Gift" self-published by Philip Van Doren Stern in 1943, which itself is loosely based on the 1843 Charles Dickens novella A Christmas Carol. The film stars James Stewart as George Bailey, a man who has given up his personal dreams in order to help others in his community and whose thoughts of suicide on Christmas Eve bring about the intervention of his guardian angel, Clarence Odbody. Clarence shows George all the lives he touched and what the world would be like if he had not existed.
