Re: Would Richard Grayson be part of this movie?
But how is that more marketing opportunities??
It depends. Red Hood is somebody that the general audience don't know a clue about. Riddler would probably be a huge actor in the role. The viral marketing could rival that of the Joker's back in 2008. The posters, the trailers, the clues, the question marks, just the color green. There's no competition with Red Hood in the marketing department. Promoting the riddler as the villain is far easier as well.
