The hour-long documentary tells the story of the discovery of the mummified remains of a prehistoric man in Italy. All footage had to be reformatted to 16:9 because a lot of the home video and archive footage was filmed in 4:3. Numerous stills and images of press cuttings required extensive resizing to achieve a seamless finish. The grading took place in-house at Lion and was overseen by executive producer Paul Gilheany. It airs Tuesday 6 March as part of Channel 4's Occult Week.
