 Cusick said that when shooting the episode "you're finishing late and starting early", but he enjoyed working with director Jack Bender because "he pushes you to, to try and go a little bit further than you think you can".The London scenes were shot in Honolulu.This led to several continuity errors, such as a British Army recruitment poster for a Scottish regiment (which would not recruit in England) featuring the word "Honour" being incorrectly spelled in the American English "Honor" and a photograph of a British soldier using an American M4 carbine and urging people to join the "military" (instead of the "army", as a British poster would say).
