Although, Isabel Fay who also appeared in the pilot was in the final episode of the first series, "The Break Up", as Fiona. The BBC then commissioned a full series, which was filmed in a studio in Glasgow. Clark wrote each episode and directed four episodes. The first series started broadcasting on BBC Three on 12 August 2008 with the first episode, "Home Sweet Home", which introduces the four main characters of Don, Abby, Karl and Eddie.
