Batman, Joker, and Harley Quinn in Suicide Squad by filmjunkee
Looks like some last bit of action was being shot for Suicide Squad as new set photos surface. Looks like the rest of that stunt sequence with Batman riding on top of the Joker’s car needed to film one last thing.
POSSIBLE SPOILERS
According to sources from the set, the sequence being shot was Batman cutting through the Joker’s roof, while the Joker decides to drive the car into water. Batman of course uses hit grappling gun to get away before it plunges into the water.
