'Arrow' casts 'Firefly' alum Sean Maher as Shrapnel
Maher is set to appear in episode 10 of the current season (according to The Hollywood Reporter). This villain is a serial bomber who descends upon Starling City for a run of terrorist attacks. Politician Sebastian Blood ( Kevin Alejandro) may find himself directly in the line of Shrapnel's fire.
Considering the normal interpretations of comic-book characters on the CW version of "Arrow," Mark Scheffer probably will not have all of the comic attributes of Shrapnel -- like being made of metal.
Maher, who also appeared in "Make It or Break It" and "The Playboy Club," is best known for the role of Dr. Simon Tam in both "Firefly" and the show's film adaptation, "Serenity." By coming on "Arrow," the actor will join his "Firefly" little sister, Summer Glau (who played River Tam on that show), as a guest star. There is no word yet on whether Glau's recurring character, Isabel Rochev, will interact with Scheffer in any way.
"Arrow" airs Wednesdays at 8 p.m. on The CW.
