The Man from Down Under (1943)

A crusty old Sergeant of the Queen's Australian army in World War I befriends a small orphaned boy and his tiny sister on the night he is to go back to Australia. The Sergeant emotionally decides to take them with him. He raises the boy and sends the girl to a prominent girl's school. As adults, the boy becomes the national boxing champion of Australia and the girl is a polished and beautiful young woman. As it is mentioned at the beginning of the movie, the boy has become orphaned, and the girl was a ward of the family, without either child's knowledge. This is a lovely film. However, the growing love between the boy and girl are a bit unbelievable beyond sibling love, but yes, it goes there. Afraid, they separate. This is an innocently presented movie about the old guy, his care and affection for the children even through adulthood, his desire to make them happy and safe, and the "miracle" that the kids are not siblings after all, since they are in love.
