Intrigo: Death of an Author (2018), Intrigo: Dear Agnes (2019) and this movie comprise an anthology trilogy. As an anthology, the trilogy is tied together by story themes - hate, revenge and nemesis - rather than by characters. The only characters common to all three movies are the not seen opening narrator, portrayed by Karen Archer, who speaks about those themes, and Doris, portrayed by Tor Clark, a server at the titular "Intrigo", a café in the fictional town of Maardam where many of the characters meet. Michael Byrne portrays Keller in both "Author" and "Samaria", Ed Cooper Clarke portrays Thomas Neuman(n)-Hansen in both "Author" and "Agnes", and Cal MacAninch portrays Erich Neuman(n)-Hansen in both "Agnes" and "Samaria", and one can only assume, although it is not implicitly stated, that in all three cases the actor is indeed playing the same character in both movies. In addition, the assumed name of the translator in "Author" and the ad copywriter in "Samaria" are both Henry Martens.
