As far as I know there was no intention of making a "Grayson" film. Problems would include rights from DC Comics, plus Warner Bros already having a Batman film series that they are quite happy with. John Fiorella was really just looking to drum up interest in himself as a film maker and it worked. He did get a credit as second unit director on a Hollywood film a few years later. DThere are thousands of short films made every year, most are barely seen by anyone except for cast/crew/family/friends. Doing a fan film like this is a trade off. Nobody can derive any profit from this because they didn't have the rights, but a "really cool" Batman or Star Wars fan film can get thousands of people watching and telling others about it.

Yes, my teacher is friends with that guy. Amazing trailer, I hope it gets made.

Even though this post is really old, I have seen it. Very top qaulity, I really hope a film is made from this.
