Abaddon

I suspect that you and I share a few favorites on the sci-fi side of his filmography, including his unsettling appearances as Matthew Abaddon on "Lost."

He appeared in only four episodes of “Lost,” and yet his mysterious Matthew Abaddon is one the series’ most memorable characters; he is barely onscreen in the “John Wick” franchise, though he registers as among its stars.

Cedric Daniels in “The Wire,” Homeland Security Special Agent Phillip Broyles in “Fringe,” hotel concierge Charon in the “John Wick” franchise and mysterious agent Matthew Abaddon, who got people to “where they needed to be,” in “Lost.”

Reddick also made an impression as Mr. Abaddon, just one of the many mysterious figures maneuvering in the background on the ABC sci-fi hit.

Beginning in 2008 he was in a few episodes of the ABC series “Lost,” playing a character named Matthew Abaddon.
