Let’s keep the Batman Vs. Superman rumor mill spinning. With all these rumors about Wonder Woman being in the new movie, we forgot that other characters from the Batman universe might show up just as well. There is an unconfirmed report floating around the digital streets that Warner Bros. and the crew of the movie, are looking for a Dick Grayson kind of actor. And being that Batman will be at an advanced age, Dick Grayson will already be dawning the Nightwing costume.
According to these sources, Warner Bros. is looking for a young John Hawkes like character. This just means they like Hawkes acting chops, and would like a 20 something year-old to have a similar acting presence as him playing Nightwing. Again, this is all unconfirmed information, but after hearing that they want to base this movie off the Dark Knight Returns novels, we are probably going to see some kind of Robin character. Let me know what you think about Nightwing in the movie.
