This is Called Dawn

The police commissioner Fasaro, repressive figure representing the established order, has on the desk of his office a volume of plays by Paul Claudel, a prominent Catholic writer. The book appears franked by a pair of handcuffs, insinuating the repulse that Luis Buñuel felt both towards the French author and his ideology. According to Buñuel himself in his memoirs, entitled "My Last Sigh", Paul Claudel's daughter wrote him a letter insulting the director for having shown in this film a book by his father next to a pair of handcuffs.
