Here is a preview of sorts:http://www.youtube.com/watch?v=gJ1Mz7kGVf0
Batman versus Ghost Rider.
That would make a great poster. If their roles are confirmed, maybe a new poster will be needed.
Aside from a couple of amateur sketches I googled, I don't see that anyone has put the two together in a quality image. One is a Marvel character and the other is a DC character. It would be like the classic Superman vs spiderman from the 70's.Aside from that, Batman is an intellectual fighter while Ghost Rider has more of a brutish style. That fits Tesla and Edison in their approach to transferring electricity over long distances.
Check out the Edison and Tesla dance off!http://www.youtube.com/watch?v=JSVfQZE5S1g
