I am at a disadvantage not having read Jack London's book. Therefore, I do not know if the credit for the end sequence should be attributed to London or to the film's co-scriptwriters--Maurizio Braucci and director Pietro Marcello. Because that end-sequence is absolutely well developed and unforgettable. The choice of music (Bach and Debussy) and the performances of two male actors--Luca Marinelli and Carlo Cecchi--are the mainstay of this film. The Venice (Best Actor), Toronto (Platform Prize), Ghent (Best Direction), Faro Island (Best Adapted Screenplay Award) international film festivals have spotted the golden veins of the film.
