Another superhero is joining the ranks of the CW’s Arrow/Flash spinoff. British actor Arthur Darvill (Doctor Who) is set to play Rip Hunter in the superhero team-up show, from Arrow creators Greg Berlanti, Andrew Kreisberg & Marc Guggenheim. Rip Hunter, described as a roguish time traveler who hides the strains of being responsible for history itself behind a facade of charm and wit, is the first of 3 DC characters that previously have not been exploited in TV, to join the new project.

The Arrow/Flash spinoff, eyed for next midseason, features three newly cast roles, two of them played by Darvill and Ciara Renée (Hawkgirl), as well as several actors who play recurring characters on Arrow and The Flash, including Brandon Routh (Arrow‘s Ray Palmer/The Atom), Wentworth Miller (The Flash‘s Leonard Snart/Captain Cold), Dominic Purcell (The Flash‘s Mick Rory/Heat Wave), Victor Garber (Dr. Martin Stein) and Caity Lotz whose role is still TBD as her Arrow character Sara Lance was killed off, with her sister Laurel Lance (Katie Cassidy) taking over as the Black Canary. Lotz’s character could be the second new-to-TV DC superhero on the new show, with the remaining new male role, which is still being cast, as third.

Berlanti and Kreisberg, who also co-created The Flash, executive produce the new series alongside Guggenheim and Sarah Schechter for Warner Bros. TV and Berlanti Prods.

Darvill, most recently seen playing Reverend Paul Coates on the praised ITV drama Broadchurch, and co-starring in Once on Broadway, is currently on stage at the National Theatre playing Long John Silver in Treasure Island. He is repped by Silver Lining Entertainment and Independent Talent Group.
