Nathan Fillion as the Green Lantern?

I think Nathan Fillion is a decent actor myself, and he’s been good in the things I’ve seen him in, like the “Serenity” movie, or the Firefly TV show from which it was based on. I even think he’s okay in that new show of his called Castle, of which I’ve only seen previews for, but hey, he looked good in it. But of course I’m not a Nathan Fillion fanatic, but there apparently lots of those around, too, and one of them made this very cool “Green Lantern” movie trailer if it starred Fillion. Good stuff. It’s never going to happen, of course, but why burst the kids’ bubbles?
