The idea for the series initially arose out of a conversation between Corden and Baynton on the set of Gavin and Stacey, four years earlier,[REF] regarding the apparent scarcity of TV sitcoms with the same level of intricate, meaningful plotting as then-current dramatic hits 24 and Lost [REF].
Once they began actually writing the series, the two quickly realised this would mean carrying through a much more ambitious project than they had anticipated, eventually leading to a significant amount of effort spent attempting to work out a believably complex, well-paced thriller plot [REF].
