The archer of Starling City is bringing one of the First Avenger’s friends on board for his upcoming season. He played Dum Dum Dugan in the Captain America and various other Marvel projects and now Neal McDonough is joining Arrow as a Season 4 regular. The Agent Carter and Agents Of S.H.I.E.L.D. actor will portray villain Damien Darhk on the CW series from Warner Bros. TV. The high tech baddie is pulled from the DC Comics world, where he was portrayed as being a twentysomething. Obviously, McDonough’s Darhk will differ from that. In the TV version he is set as an old foe of Ra’s Al Ghul, a major figure in the onscreen DC Universe.

Arrow logo the CWMcDonough is repped by Paradigm and Luber Roklin. Arrow‘s fourth season debuts on October 7.

The casting announcement comes one day ahead of WBTV’s Comic-Con mega-panel in Hall H. The 8-11 PM gathering is set to feature casts and creative from Arrow as well as The Flash, the upcoming Supergirl, Legends Of Tomorrow and Gotham. No word if the TV Darhk will be appearing on Flash or Legends too.
