Well, we still don't know if he'll be Nightwing, but looks like reports that Adam Driver is very popular over on the Warner Bros lot is totally true, since he's just been cast in a different sort of cool project over there.
The Wrap reports Driver has joined Michael Shannon, Joel Edgerton and Kirsten Dunst in Jeff Nichols' next, a sci fi thriller called Midnight Special. The chase actioner follows a father and his 8 year old son on the run after they discover the kid has developed super powers.
While The Wrap say his role is under wraps, we have some details. Driver seems to be a fit for the role of Paul, an NSA agent on their tail. Though his team is bent on capturing them, Driver's character is reluctant, as he genuinely cares for the boy and wants him to be with his father.
Sounds very intriguing, but let's face it, this director with this cast was already intriguing enough. Now, The Wrap goes on to mention Midnight Special and Batman vs. Superman will both be filming around the same time early next year, but make of that what you will.
