Of course there is no plans for this movie that can be found anywhere. But it definitely looks like it's from Warner Brothers.
Could this be the long awaited sequel to James Cameron's Aquaman? You know the movie they were suppose to be making during Entourage? Most people think this a prank poster for the upcoming film version OR is it a prequel to Batman, Superman and their Superfriends? What do you think?
