Los Angeles: `Girls` star Adam Driver is the frontrunner to bag the role of Batman`s sidekick Dick Grayson aka Nightwing (Robin) in Zack Snyder`s superhero sequel `Batman vs Superman`.
The 29-year-old actor apparently fits the description of Nightwing, Grayson`s post-Robin alter-ego. Affleck will play an older and world-weary Batman in the sequel, reported the Wrap.
Two other actors are also in the fray to play Grayson, the Caped Crusader`s former sidekick, who`s been estranged from Bruce Wayne for years in the movie.
Henry Cavill is set to reprise his role as Superman alongside his `Man of Steel` co-stars Amy Adams and Laurence Fishburne.
Warner Bros is currently searching for a female star for `Batman vs Superman` where former Bondgirl Olga Kurylenko is the frontrunner.
It is also rumoured that the coveted role could be of Wonder Woman or her alter ego Diana Prince.
