Casting breakdowns for CW's proposed new Green Arrow t.v. series has leaked, revealing which characters from the DC Comics universe we can expect in the pilot and a lot of information on character and potential plot details if it is greenlit for series. Obviously Oliver Queen is our lead, referred to as a '27 year old reformed bad boy' who is a 'thoughtful master of the bow with a ferocious determination to make a difference' with info on his shipwrecked origins. However interestingly the second billed character is Dinah "Laurel" Lance, who DC Comics fans will know as Black Canary. Of course we don't know for sure this means that Lance's superheroine alter ego will be part of the show, but we would think it was pretty likely otherwise they would have just created a brand new character specifically for the show. She may not be Black Canary from episode 1 but we don't think it will be too long until we do see her. The full character breakdowns are below, courtesy of TV Addict; Oliver Queen A 27 year old reformed bad boy, who after having spent five years shipwrecked on a tiny, brutally dangerous island in the South China Sea returns to town a different man. Or to be more specific, a tortured, thoughtful master of the bow with a ferocious determination to make a difference. Dinah "Laurel" Lance 28 years old, smart sexy, Laurel is a legal aid attorney determined to use her life as a one-woman war against the 1% following the death of her younger sister Sara. A sister, who as luck would have it, just so happened to have died aboard Olivers yacht. Tommy Merlyn 28 years old and devil-smooth, Tommy is a trustafarian like Oliver, a spectacularly rich young man whose life revolves around parties, clubs, liquor and lots of anonymous sex. Unlike Oliver, he cant seem to understand his former best friends sudden change of lifestyle and direction. Moira Queen 48 years old, a beautiful woman, Olivers mother Moira is a very wealthy woman who is not used to being shaken. Having remarried during the five years that former husband Robert and Oliver were both presumed dead, Moira has had free rein over the Queen billions. Not surprisingly, shes deeply interested in learning whether or not Robert will also return unexpectedly, to ruin her present marriage and go over the books with a fine-tooth comb. John Diggle 35 years old, African-American, Diggle is really, really big, a former military man who served with the Army Rangers in Afghanistan, and has been a bodyguard for hire for the last four years. Hired by Moira to be Olivers chauffeur and protector, Diggle soon finds he is trapped in a battle of wits, as Oliver repeatedly eludes his protection. But in fact, Diggles primary conflict is one of loyalty he has to show that hes working for Oliver, not Moira, before Oliver will give him a smidgen of trust. Thea Queen 17 years old (suggest 17-22 years), Olivers Lolita-esque sister, Thea was a 12 year old girl when he went on his infamous yachting voyage but now shes a celebutante whos testing the boundaries of acceptable behavior. Thea loved her big brother with all her heart, and is delighted to have him back in her life but shes spreading her wings, and is unprepared for Oliver to become the Bad Cop in the family, restricting her access to boys and drugs. Green Lantern movie writers Greg Berlanti, Marc Guggenheim and Fringe/Warehouse 13s Andrew Kreisberg will write and produce the pilot, which if successful would get a full series. Casting is expected to start immediately for the pilot. Our full article detailing CW's plans when the show was first announced last week you can find HERE.
