IGN reports that actor Nick Tarabay has been cast as Captain Boomerang for season three of Arrow — and it’s not a huge stretch to guess that he’ll eventually cross over to the Flash series as well. Tarabay is best-known for playing Ashur on the television series Spartacus.
The TV series’ Captain Boomerang is described as 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.” It is reported that he’ll appear in episodes 7 and 8 of Arrow; as IGN notes, episode #8 is the crossover with the Flash series.
There have been unofficial rumblings of a potential Suicide Squad series for a while now, and when I saw Arrow‘s Stephen Amell at Fan Expo last month he said he wanted the team to guest-star in multiple episodes. One wonders if Digger will eventually be joining the Squad.
