Sissi

A very young and innocent girl marries the powerful ruler of the most powerful empire on earth. Why? Because she loves him dearly. If that is not sweet. And it is also not far from the truth. Of course it helps that she was a little princess - only of Bavaria but of royal blood (I think). Of course everybody loved her - well, she got killed by someone eventually, but that is not in the film and it does not prove anything anyway. If you know Romy Schneider only from her later (mostly French) films do not even try to imagine how beautiful and charming, well sweet she was. She made two sequels. All three films will be valued as the highest art in the million years to come by anyone who can enjoy a fairy tale.
