In France, the title "L'empreinte de l'ange" had to be changed in 2010 and became "L'empreinte" after a trial, as the initial title was already used for an unrelated novel, even though "l'empreinte de l'ange" is an existing French expression for "philtrum" (coming from Jewish mythology).
Remade in 2019 as the English language "Angel of Mine" starring Noomi Rapace and Yvonne Strahovski.
