Ian Somerhalder (Lost,Vampire Diaries)-Dick Grayson(Batman)
Dick Grayson,the first Robin, Taken by Bruce Wayne when his parent were killed, found out that Bruce wayne and Batman were the same and then Batman took him under his wing as Robin,the Boy Wonder But After a few years, as he grew older, He came out of the Batman's shadow and become NightWing overcoming challenges with successes and failures and when Bruce Wayne was "killed" he become the new Batman. The Prodigal son of the family. Ian Somerhalder is The fan favorite for this character and he has acting chops and a dark look to him and he kinda does look like Dick in some incarnations!
Jensen Ackles (Supernatural,Smalville)-Jason Todd (Red Hood)
The Wayward son of the family.the second Robin after Dick. Hot headed, wild and violent, he was killed by the Joker. Later resurrected as an insane vigilante using the Jokers previous identity. He is Dick Graysons equal in combat and a master in weaponry. Jensen Ackles is anothe favorite fo this role and after under the Red Hood he is my only pick for Jason.
Thomas Dekker (The Sarah conner chronicles)-Tim Drake (Red Robin) (Thanks Leee777)
He is the peacemaker of the family, he deduced Dicks and Bruces identity by seeing dick do a acrobatic move that he saw dick once do. Tim is a genius, he probably has surpasses Bruce as a detective. He is more temperamental and rational then his "brothers". Thomas Dekker is a good actor and can do justice to Tim Drake.
Kodi Smit Mcphee (The Road,Let me in)-Damien Wayne
He is the little,mischevious kid of the family and is the illegimate son of bruce and talia al ghul.he is the perfect specimen via experiments performed on him. He has been trained to kill, he is violent and only cares about himself and in my opinion a cool character. Kodi Smit McPhee was good is The Road, so i have heard and after watching the trailer for Let Me in, he can play dark characters,he is 13 years old, but damien is sometimes drawn as 12 or 9 years old.
