Yeah, there’s a lot of genre blending around fantasy. Like Star Wars is a mix of sci-fi and fantasy. As is a lot of superhero stuff, where you have science heroes existing right alongside actual gods.

I think what OP is talking about his Tolkien-style medieval fantasy, which is very hard to do well because it costs so much. Also if you’re adapting a book, there’s always a section of die-hard fans out there who will absolutely crucify you if you get things wrong. Presumably that makes studios nervous.
