6. 1946: 'It's a Wonderful Life'
It's a Wonderful Life isn't just a classic holiday film, but it's a beloved piece of movie history. While a remake could be easy to achieve - most feel-good movies transcend decades and translate easily into whatever year they're in - this one is just too much of a classic to redo. Why would anyone put on the remake in December when the 1946 version is the usual go-to tradition?
