Written by Boileau-Narcejac (Diabolique), 'Pleins Feux sur l'Assassin' is a mystery movie set in a castle of the Middle Ages. The screenplay is not so original and I think that the only scene worth my time was the first scene with Pierre Brasseur.
This movie features one of the director's and cinema's great set pieces. Franju creates a vivid and spooky scene using nothing but a spotlight and voiceover. Absolutely brilliant scene in a nifty little murder mystery.
