in the seventh. The third series also sees a number of recurring characters and guest appearances. Megan Dodds returns as CIA liaison Christine Dale in the first episode. Tim McInnerny recurs as JIC chairman Oliver Mace. McInnerny was better known as a comedic actor, particularly for his role in Blackadder, but the producers felt that quality made Mace a more menacing character. Richard Harrington plays Will North, Zoe's boyfriend turned fiancé. Ian McDiarmid guest stars as Fred Roberts. The producers noted that McDiarmid played Roberts with the right amount of vulnerability, strength and stubbornness. Indian actor Anupam Kher appears as Harakat in "Who Guards the Guards?". Oyelowo stated that Kher had an "instant quality of likeness," which can make the audience sympathise with Danny after Harakat is killed in the episode. "Love and Death" sees two guest stars who were personally involved with the cast and crew. Dermot Crowley, portrayer of Eric Newland, was the husband of one of the series' casting directors, though Crowley still had to earn his role. Barnaby Kay plays Ruth's potential love interest; Kay was Nicola Walker's real-life boyfriend, now her husband. Andy Serkis guest stars as Riff in "Celebrity". Created as an eccentric character, the producers believed it would fit in with Serkis' acting. Owen Teale appears as Robert Morgan in "Frequently Asked Questions". Producer Andrew Woodhead stated that Teale has a "strong physicality" that would make him a suitable equal for Adam. The series finale "The Suffering of Strangers" saw the introduction of two new characters that would receive expanded roles in the fourth series. Raza Jaffrey portrays Zafar Younis. Jaffrey's first day of filming required him to perform a difficult speech he had to "launch into." In addition James Dicker portrays Wes Carter, Adam and Fiona's seven-year-old son. The producers held discussions whether to introduce Wes in the finale or in the fourth series; they eventually chose the former.
