This season the big bad of Arrow is Ra’s Al Ghul who will be played by Matt Nable. You can see Stephen’s official Twitter post about the new cast addition below and even better you can have a look at the new trailer to Season 3.
The tone looks lighter this season which I personally welcome and it looks like Oliver finally gets together with Felicity.
ARROW premieres on October 8th on The CW.
Please welcome Matt Nable to Arrow. You know who he’s playing. pic.twitter.com/f0I7tmujiD
