In 2003, Willy Brandt's son, Matthias Brandt, took the part of Guillaume in the film "Im Schatten der Macht" ("In the Shadow of Power") by German filmmaker Oliver Storz. The film deals with the Guillaume Affair and Brandt's resignation. Matthias Brandt caused a minor controversy in Germany when it was publicized that he would take the part of the man who betrayed his father and made him resign in 1974. Earlier that year - when the Brandts and the Guillaumes took a vacation to Norway together - it was Matthias, then twelve years old, who was the first to discover that Guillaume and his wife 'were typing mysterious things on typewriters the whole night through'.
