The Hollywood Reporter has revealed that actor Arthur Darvill, best known as Rory Williams in Doctor Who, has been cast as time traveler Rip Hunter in the upcoming ‘Arrow/The Flash’ spinoff series.

The character is described as “a roguish time traveler who hides the strains of being responsible for history itself behind a facade of charm and wit.”

Darvill joins a cast that includes Brandon Routh, Wentworth Miller, Dominic Purcell, Victor Garber, Caity Lotz, and Ciara Renée. 

‘Arrow’ creators Greg Berlanti, Andrew Kreisberg and Marc Guggenheim are working with Warner Bros. Television and Berlanti Productions to develop the spinoff.
