When talking about why Gordon stayed behind in Gotham after the villains took over, McKenzie said:
"He is going to be the last guy down with the ship." I think that the pressure becomes more and more and more intense and he becomes a bit like Atlas, trying to carry the well-not quite literal but the figurative weight of the world on his shoulders. The pressure just goes more and more intense. Which is interesting is it not to be successful, which is a big one in the middle of the season. A decision he makes in the heat of passion that has important ramifications for him and others in the future. "
McKenzie also said the final season will be packed with Easter eggs that hardcore Batman fans will notice:
. I will put it this way, a lot of the questions we get asked on comic cons like 'when you gonna do this, when you gonna do this.' Well, right now! Right damn now we're gonna do them as we do not have any more time. "
The series also Morena Baccarin as Leslie Thompkins, Sean Pertwee as Alfred, Robin Lord Taylor as The Penguin, Erin Richards as Barbara Kean, Camren Bicondova as Selina Kyle / the future Catwoman, Cory Michael Smith as Edward Nygma / the Riddler, Jessica Lucas as Tabitha Galavan, Drew Powell as Butch Gilzean / Solomon Grundy, Alexander Siddig as Ra's Ah Ghul, and Crystal Reed as Sofia Falcone
