Blu-ray earns its stripes

Peter Greenaway’s A Zed & Two Noughts, recently released on Blu-ray disc by the BFI, proves that the high-definition format isn’t just for blockbusters: it could have been invented for the British director’s first collaboration with the legendary cinematographer Sacha Vierny, a partnership which made explicit Greenaway’s debt to French auteur Alain Resnais and introduced the meticulous colour-coding that would characterise later films such as The Cook, the Thief, his Wife and her Lover.
