Conleth Hill
As the format of "Inside No. 9" requires new characters each week, the writers were able to attract actors who may have been unwilling to commit to an entire series. In addition to the writers, "Tom &amp; Gerri" starred Gemma Arterton and Conleth Hill. The flat in which the episode was filmed, with its boardgames and "misery", was, for Shearsmith, similar to the flat once shared by the writers. The episode was filmed in winter, and Pemberton described a "grim" atmosphere during filming. He also said that he hated the wig and beard he wore to play Migg, which irritated his skin. David Chater, writing in "The Times", said that the hair meant Migg "has an eerie resemblance to the Cowardly Lion from the Wizard of Oz - only not nearly as benign".
