Ooo. Books made into movies. What a double-edged sword. We've all seen books turned into movies, some done badly, a bunch done marginally, and precious few done brilliantly well. So as a reader, I have such mixed emotions about books adapted into movies. As an author who'd like to have a book adapted into a movie, I STILL have mixed emotions. Part of this is because one of my SFR idols had a book optioned. The script was written and approved. Shooting started. (Somewhere in there, I hope she got paid.) She even brought the cast to conferences with her to help hype the production.
I've never seen it. I don't know for sure what happened, but I can guess the production fell apart somewhere. From what tiny bit I know about the business of making films and TV - lots of projects die before being bought. Tons more get bought and never made. The ones that get made might make it into the can, but never again see the light of day. Who knows where that SFR movie died? What I'm trying to say is that while authors might dream of the money that might come with a movie deal, there's more investment than cash and knowing that it could crash and burn at any time is -- hard.
All of that said, if I could see a single book turned into a movie, it would be the first one, Enemy Within. It's just the book I saw most clearly. The plot feels super focused and the romance tight and to the point. It would be tough, though. The CGI would have to be on point for my bad guys. Of course the technology exists to do the job. Witness Star Wars, the MCU, etc. It's the price point that might be an issue. But yes. That book. It's a fun book and a fun story. If you don't count the dead bodies.
I mean. Space pirates. Enemies to lovers. Everyone out to get the heroine and not even she knows why? What's not to like out here among the spaceships and bug-eyed monsters?
