Seifert began to feel pressure midway through filming, when she realised that "the whole game is hinging" on her performance.[27] She described the shoot as "intense" and "rather exhausting", and felt as if she was "subtly being scrutinised" by Barlow, which helped her performance.[33] Barlow also felt that the intensity helped Seifert's performance, taking cues from director Alfred Hitchcock, who would upset his actors in order to achieve the greatest performance.[31] Seifert felt that there were small nuances in her performance that may have "added some twists and turns" for the player that Barlow had not anticipated.[33] The game's seven police interviews were filmed roughly in chronological order[7] over five days,[33] in a process that Barlow called "natural".[22] Like Seifert though, Barlow thought the shoot was intense, remarking "at the end of the shoot, it was just a huge relief it was all over and we hadn't forgotten to record or anything."[6] Barlow travelled to Seifert's home county of Cornwall to film.[33] He felt that finding the locations for the interrogation rooms was the simplest part of production, because "everywhere has crappy looking rooms", with footage being recorded in a council building in Truro.[4][7] When filming was complete, Barlow wanted to give the impression that the videos had been recorded in 1994, but found digital filters were unable to capture this time frame appropriately. Instead, he recorded the footage through two VHS players to create imperfections in the video before digitising the video into the game.[21][9]
