Old Heidelberg

Karl Heinrich is the heir to the throne of the small European principality of Rutania, but he's a lonely child, not allowed to play with other children and knowing little about life outside the castle. When he reaches maturity, he is sent to attend the University of Heidelberg, and finds fellowshi with classmates and a blossoming love with Katie Ruder, his only friend during childhood and the niece of an innkeeper. However, political turmoil in Rutania forces him to return. War is declared. Heinrich returns to Heidelberg one last time to bid a somber farewell to his beloved Katie.

Directed by John Emerson, Old Heidelberg leans on a strong ensemble — Wallace Reid, Dorothy Gish, Karl Formes — to carry a story that balances spectacle with character.

The film landed with audiences for its craft and performances, and remains one of the most talked-about romance titles of 1915.
