10. Matt Long

Matt Long would create an interesting character, he is only 5’9″, his looks is of a gentle, lighthearted person, and even with these features he would resemble an older Robin (a.k.a Nightwing). He has made it into the world of comic book adaptations before as young Johnny Blaze in Ghost Rider.

Matt could put less of a dark tone on the character, but it depends if that is required.

Regarding his acting, you may know Matt from TV Series like Helix or Mad Men. Many fans expect Nightwing to be more of a newcomer, and Matt Long is not that of a household name.
