Val Guest, who had directed "The Quatermass Xperiment", returned for "Quatermass 2". Guest once again sought to create a film that felt as real as possible, using many cinema vérité techniques such as hand-held cameras. He was assisted in this respect by the moody, overcast cinematography of director of photography Gerald Gibbs, who also made extensive use of day for night photography for the film's climactic scenes. Guest planned each day’s shooting carefully, creating meticulous storyboards detailing all the shots he wanted to make that day.
