 In the opening credits, we are correctly informed that the film is based on  the novel "Pop. 1280"; but during the end titles, we are informed that it  is based on "Pop. 1275". This is consistent with the official title  retained for the translation into French, which is "1275 Ames" (literally:  "1275 Souls"), and which reflects the fact that 5 people have died during  the course of action.
