Adam Driver is reportedly the producers' top choice to play Nightwing in Batman vs Superman.

The 29-year-old actor, who plays Adam Sackler in the HBO comedy Girls, is reportedly the first choice to play Batman's sidekick, Dick Grayson, aka Nightwing, who was formerly Robin. 

In the Man of Steel sequel, which will be directed again by Zack Snyder, Grayson will have been estranged from Bruce Wayne for years.

Ben Affleck is set to star as Batman opposite Henry Cavill as Superman. Amy Adams, Diane Lane and Laurence Fishburne are also set to star in this highly anticipate superhero movie. 

Batman vs Superman is due for release in July, 2015.
