Colton Haynes cast in 'Arrow'

Colton Haynes has been cast in Arrow! And he's going to play one of my favorite characters ever in the DC Universe! I am so excited.

Colton announced that he was leaving Teen Wolf a couple of months ago.

From TV Guide:

Ya might wanna sit down for this one, Arrow fans. TV Guide Magazine has learned exclusively that the CW show — which is already exceeding its hot limit with Stephen Amell, Katie Cassidy and Colin Donnell — has just hit a major bull's eye by signing Teen Wolf alum Colton Haynes.

"We were big fans of Colton from Teen Wolf and we are thrilled he's joining Arrow," says executive producer Greg Berlanti of the actor, who is set to begin appearing on the show in 2013 as none other than Roy Harper.

DC Comics aficionados will recognize that name as the young marksman who has been known as, since his debut in 1941, the Green Arrow's sidekick Speedy, Teen Titans member Arsenal, and the Justice League's drug-addicted, one-armed Red Arrow. While details on this iteration's possible secret identity are being kept, well, secret, Haynes' Harper is being described by The CW as "a handsome, street-savvy, teenager from 'the Glades,' the harsh, poverty-stricken portion of Starling City."
