Actor Jason O'Mara has been cast as the as-yet-unnamed new Director of S.H.I.E.L.D. beginning with ABC's fourth season of Agents of S.H.I.E.L.D., according to Deadline. Details on who O'Mara's character actually is are mum, but the online Hollywood trade describes the character as someone whose "Marvel roots go back to the 1940s."
“Bringing Jason into the mix as the New Director of S.H.I.E.L.D. forces everyone, particularly Coulson, to reevaluate their role in the Agency,” said Jeph Loeb, Marvel's Head of Television. “Jason has both the physical presence and acting dynamics that will connect with and challenge even the most loyal agent.”
O'Mara starred in the recent USA Network series Complications, and was also the lead in ABC's short-lived Terra Nova and Life On Mars series. For genre fans however, he might best be known as the voice of Batman - voicing him in seven of the recent DC animated films including Batman vs. Robin, Batman: Bad Blood, as well as the upcoming Justice League Dark.
Agents of S.H.I.E.L.D. returns for its fourth season September 20 on ABC.
