as Old Shepherd Anthony Eustrel as Hooper Herbert Lomas as Mr Campbell Graham Moffatt as RAF Sergeant Petula Clark as Cheril, the precocious daughter of the Robinsons Making their third appearance in I Know Where I'm Going! were director Michael Powell's golden cocker spaniels Erik and Spangle, who had previously appeared in Contraband (1940) and The Life and Death of Colonel Blimp (1943), and went on to be seen in Powell and Pressburger's A Matter of Life and Death, also known as Stairway to Heaven (1946). Production Development Powell and Pressburger wanted to make A Matter of Life and Death but filming was held up because they wanted to do the film in colour and there was a shortage of colour cameras. (Technicolor cameras and technical specialists were mostly in Hollywood during the Second World War.) Pressburger suggested that instead they make a film that was part of the "crusade against materialism", a theme they had tackled in A Canterbury Tale, only in a more accessible romantic comedy format. The story was originally called The Misty Island. Pressburger wanted to make a film about a girl who wants to get to an island, but by the end of the film no longer wants to. Powell suggested an island on Scotland's west coast. He and Pressburger spent several weeks researching locations and decided on the Isle of Mull. Pressburger wrote the screenplay in four days. "It just burst out, you couldn't hold back," he said. The movie was originally meant to star Deborah Kerr and James Mason but Kerr could not get out of her contract with MGM, so they cast Wendy Hiller. Hiller was originally cast in the three roles Kerr played in The Life and Death of Colonel Blimp but had to withdraw because she got pregnant. Six weeks before filming, Mason pulled out of the movie, saying he did not want to go on location. Roger Livesey read the script and asked to play the role. Powell thought he was too old and portly but Livesey lost "ten or twelve pounds" (four or five kilos) and lightened his hair; Powell was convinced, but Livesey was appearing in a West End play, The Banbury Nose, during the shoot, so he was unable to go on location. Filming Shooting took place on the Isle of Mull and at Denham Studios. It was the second and last collaboration between the co-directors
