Rumour: Nightwing and Wonder Woman to appear in Batman vs. Superman?

Major rumours have surfaced regarding Batman vs. Superman today, with various sources claiming that both Nightwing and Wonder Woman may feature in the film.

Latino Review , usually a reliable source for superhero news, reports that Warner is searching for potential actors to play an adult Dick Grayson, now acting as the vigilante Nightwing.

The casting brief is apparently "a young John Hawkes type", creating the intriguing image of a Hawkes / Affleck double-act.

Meanwhile, Forbes is claiming that Wonder Woman will also appear in the film, with Schmoes Knows also reporting that Olga Kurylenko has already tested for the role.

Whether or not any of the above actually pans out remains to be seen, but in the wake of Affleck's casting, we're inclined to believe that anything's possible!

Directed by Zack Snyder, Batman vs. Superman will open in the US on 17 July 2015, with a UK date to be announced in due course.
