Jensen Ackles can play the hot head,the cocky yet heroic Green Arrow with a dark edge as he has played many times on supernatural.
Lauren Cohan,with a hair dye can play the strong yet hard hitting Black Canary .
Ralph Fiennes is an awesome actor and my only choice for green arrows mentor cum villain, MERLYN.
I couldnt think of anyone else and i come across Jason Statham and said ''WHY NOT'' for CONSTANTINE DRAKON.
SEAN BEAN IS BADASS AND HE IS AN AWESOME ACTOR SO I CHOSE HIM AS DEATHSTROKE THE TERMINATOR.
PAUL BETTANY IS PERFECT FOR THE ROLE of COUNT VERTIGO.
