Oddly, the two main characters, played by Sara Mortensen and Olivier Sitruk, are named slightly differently in the credits than they were in Murders in Rochefort (2019), the previous film in the series, Going from Emma Thélier and Adrien Klévec to Emma Thellier and Adrien Klevec, with no more accents and a double L for Emma's surname.
The film continues as the end credits roll on.
