This film, Orson Welles' personal favourite, starts a weekend of screenings devoted to the director at Curzon Bloomsbury. You can find the full details on this page on the cinema's website. This will be the first screening of the restored 50th anniversary edition (out on DVD on 29 June).
Chicago Reader review:
Orson Welles's 1966 version of the Falstaff story, assembled from Shakespearean bits and pieces, is the one Welles film that deserves to be called lovely; there is also a rising tide of opinion that proclaims it his masterpiece. Restrained and even serene (down to its memorably muddy battle scene), it shows Welles working largely without his technical flourishes—and for those who have never seen beyond his surface flash, it is ample proof of how sensitive and subtle an artist he is. With Keith Baxter, John Gielgud, Margaret Rutherford, and Jeanne Moreau.
Here (and above) is the memorable battle scene.
