Variety reports he'll play John Diggle, a military man turned bodyguard who's trapped in a battle of wits, loyalty and trust when he's hired by the wealthy Moira Queen to protect her son Oliver, who repeatedly eludes him. Stephen Amell, who had a prominent role on HBO's "Hung," was cast last week as Oliver Queen.
Created by "Green Lantern" screenwriters Greg Berlanti and Marc Guggenheim and "Fringe" co-executive producer Andrew Kreisberg, "Arrow" is described by CW executive Thom Sherman as "very provocative and sophisticated and edgy," and "not as comic book-y as 'Smallville' or other [superhero projects] from other networks."
"He doesn't have any superpowers, he's a very grounded character like a Jason Bourne - we use the term 'mambo,'" Sherman recently told Entertainment Weekly. "His skill-set is that he's an archer, but he also have physical strength and prowess. He's clever and able to devise ways of taking down a bad guy that are unique and fun to watch."
Berlanti, Guggenheim and Kreisberg, who previously worked together on ABC's "Eli Stone," will co-write and executive produce the pilot for Warner Bros. Television. David Nutter ("The Pacific," "Game of Thrones") will direct.
The 40-year-old Ramsey, perhaps best known for his role as confidential informant Anton Briggs on Showtime's "Dexter," currently appears as New York City Mayor Poole on CBS's "Blue Bloods."
