4. Tyler Hoechlin

He was on the shortlist to play Batman, but Snyder was looking for an older actor and he is only 26. With a look that is hard to forget, Tyler would make a very interesting and highlighted appearance alongside Batman. Wouldn’t he be the right fit for the role?

Tyler Hoechlin made his first big appearance in Road to Perdition as the son of Michael Sullivan (Tom Hanks) in 2002. After few more film gigs, he landed in MTV’s hit show Teen Woolf portraying Derek Hale. Given his role in Teen Woolf (a werewolf) he is perfectly fit for the role of Nightwing. His fit body and age recommend him as well.
