These are my suggestions for Nightwing, Wonder woman and Lex Luthor.
Dick Grayson/ Nightwing – Garrett Hedlund
Dick Grayson is rumoured to appear in Batman vs. Superman and we got 3 choices for him Adam Driver (NO!!!!!!) or Ezra Miller (No!!!!!) or Penn Badgley (My Choice out of the 3 choices so far) but my 1st choice for Dick Grayson is Garrett Hedlund.
I know Hedlund isn’t original but he is a really talented actor who could easily pull of this role. He has the look, built and the acting ability to pull of Nightwing He has been in movies like Troy:Legacy, Tron Legacy, Inside Llewyn Davis & on the Road. He would make a pretty good Nightwing.
Wonder Woman is rumoured to cameo and my pick for her is….. Gemma Arterton
I have seen her cast a few times before and I think she would make a pretty good Wonder woman. Some people suggest Jamie Alexander from Thor but which is part of Marvel but then again so was Ryan Reynolds . I think Gemma Arterton has the acting talent to pull of Wonder Woman.She has been in Quantum of Solace, Clash of the Titans, Prince of Persia: The Sands of Time and Hansel and Gretel: Witch Hunters.
Lex Luthor
I have a lot of picks for Lex but my main 3 are Ralph Fiennes, Luke Evans & Richard Armitage.
Ralph Fiennes is a talented actor who would make a convincing Lex. I have seen him cast a few times before.He has been in movie like Harry Potter,Clash Of the Titans,Schindler's List and Coriolanus.
Luke Evans is also another talented actor who would make a pretty good Lex. He has proven himself is all of the movies he has been in and he is good friends with Henry Cavil. Evans has been in movies like Immortals, No One Lives, The Raven, Fast & the Furious 6 and he is in the upcoming Hobbit movie.
Richard Armitage is a good actor who would make a convincing Lex. He was my pick for Batman. He can be intense , intelligent & intimidating and I think that’s what Lex should be like. He has a small role in Captain America but I dont think anyone would really take notice of it. He has been in Strike Back aswell the The Hobbit:An Unexpected Journey and is in the sequel.
