If you change the abbreviation SF so it also includes "Speculative Fiction", would that help?

This isn't unique to Hollywood. The recent Charles Stross book I read, "The Family Trade" can found on the Fantasy shelves of Chapters, and not the SF one. While there is the fantastical element of the secret of the Family, everything else cannot be considered fantasy in the strictest sense (unless, of course, you frame SF as a subset of Fantasy).
