There are few topics concerning fans of the DCU more than the question of Batman right now. As Matt Reeves continues to forge his own path with The Batman and its universe, people are waiting to see what James Gunn will do with the Caped Crusader.
Speaking on the 2 Bears, 1 Cave podcast (at about 51 minutes in), Gunn spoke about the troubles associated with Batman. He opened by talking about how many fans want so many different things, such as blue and grey colour designs or white eyes in the cowl.
