Why Is There No Question Mark In The Title?

Obviously, I’m not really asking a question. I’m pointing out that the film’s title leaves us with a choice: (1) someone named “Who” framed Roger Rabbit, or (2) we don’t know who framed him, but the author of the title was too lazy/illiterate/both to make the title interrogatory by adding “?”

This has bothered me for a long time. Perhaps the error begins with the novel that inspired the film, in which case not only is the author to blame, so are his editors at the publishing house.

Because there is no character in the film named Who, I have to conclude that this is another example of nobody giving a damn about correct use of language. Y’know, the kind of folks who think that “Whatever” is an acceptable catch-all reply to any other statement, question or sneeze.
