Trivia

During the second season Modus became the most successful Scandinavian TV series on Sweden's TV4 in 25 years, with an audience of 1.2 million.

Melinda Kinnaman, sister of Joel Kinnaman who appeared in the US remake of The Killing (2011), said she was drawn to the role of Vik, after having just had a baby, because of the lead character's complexities and flaws and the fact that the show grapples with differing family setups, from the single mother to gay couples raising children.

Anne Holt, author of "Pengemannen" from which season 1 is adapted from, is a former Norwegian justice minister.

The main cast are all credited in the title sequence of each episode, no matter if they appear in the episode or not.

Screenwriters Mai Brostrøm and Peter Thorsboe said just having the one book ("Pengemannen" by Anne Holt ) had ensured Modus could delve deeper into the personal struggles of its characters than other popular crime dramas, as well as employing the slow and deliberate pace that is central to the popularity of Scandi-noir.
