Well, Arvens didn't confirm my answer, but I'm certain enough about it to post the next question anyway:
Exactly 90 years ago, on February 8th 1915 a movie was released in the United States which was the first movie that covered a whole evening (it lasts about 3 hours). The movie deals with a part of the American history, but the content is "questionable" to say the least.
Please give the title of the movie and (if you want a special cheer) the alternative title which was discarded, as it showed too obviously the "political message" of the movie.
