‘Arrow’ Season 2 Adds ‘Firefly’ Star Sean Maher as DC Villain Shrapnel
'Arrow' has long had a history of picking top genre stars for its own, and it seems the acclaimed CW drama will be re-lighting the 'Firefly' once more. Following Summer Glau's turn on the Green Arrow drama as DC villain Isabel Rochev, Glau's former onscreen 'Firefly' brother Sean Maher will portray the villainous DC bomber Shrapnel in episode 10.
