2. 'Miracle on 34th Street'
The 1947 film, about a man who says he's Santa Claus and the little girl (played by a young Natalie Wood) who believes in him, garnered actor Edmund Gwenn a Best Supporting Actor Oscar for playing St. Nick. The film, which has become a Christmas classic, was released in May despite its Yuletide themes – 20th Century Fox studio chief Darryl Zanuck was unshakable in his belief that more people went to the movies during the summer. So it's impossible to tell from many promotional materials for the film, including the trailer, that the movie is centered around the holidays.
