Nick Tarabay (Star Trek Into Darkness) has landed a multi-episode role as Digger Harkness (aka Captain Boomerang), EW can exclusively report.
On the page, he has also been associated with the Suicide Squad. On Arrow, Harkness will be a former A.R.G.U.S operative, highly skilled in martial arts and espionage, with a deadly thirst for vengeance against his former employers.
The character will be introduced in the seventh episode of the upcoming third season, and then continue in the eighth episode — which is when spin-off star The Flash crosses over into Starling City.
