Arrow has added yet another DC Comics character to its upcoming third season.
Medium's David Cubitt has been tapped to guest-star as Mark Shaw, otherwise known as Manhunter, TV.com has confirmed. Shaw is an A.R.G.U.S. operative in Corto Maltese who crosses paths with Diggle.
Cubitt joins a long list of guest-stars coming to Arrow in Season 3, including Brandon Routh as Ray Palmer, Charlotte Ross as Felicity's mom, and J.R. Ramirez as Wildcat. The series has not yet cast the highly anticipated new villain Ra's al Ghul.
The casting was first reported by The Hollywood Reporter.
