Hello and welcome! I'm DinosaurNothlit, but call me DN or Dino. It's nice to meet you.
Yeah, we all hope for a movie, but I wouldn't hold my breath. It would be a big-budget undertaking to really do it justice, and there just isn't enough of a potential fan-base for it. Yeah, the fans that Animorphs has are really dedicated ones (hence why there's still an active forum this many years later), but dedication doesn't rake in the box-office bucks.
