I think the movie is black and white. Was made in the 40's or up to the 60's maybe. The main character is a man, and he goes by a shortened version of his actual last name. Like Pennywise, or something. A young boy comes to live with him, I think it's his nephew. I've searched for a few years online and cannot figure it out. Please help me identify this movie. I would like to see it again.
I think it's Pimpernel Svensson. The main character name is Anders 'Pimpernel' Svensson.
