Was Wing Commander originally a video game? I remember there was an animated series, but I was under the impression the game was based on that. I've never actually played the game, though, so I could be wrong.
There were some Final Fantasy-ish elements to TSW, but I still think they only put a Final Fantasy title on it in order to profit for the name. If they were going to base a movie on an actual Final Fantasy game, I'd like to see it done with Final Fantasy 6. Or another Square game, Chrono Trigger, would make a good movie.
