Your example of Lazlo as protagonist is actually an example of him as Main Character. I certainly don't think he's the Main Character of the story.
If Casablanca is two stories, then why not argue that Rick is the protagonist of the love story and Laszlo (sorry about the previous misspelling
) is the protag of the resistance story?
