This 35mm screening, in the Big Screen Classics season at BFI Southbank, is also being screened on November 17th. Full details here.
Personally, this is my favourite film by Orson Welles and my appreciation and understanding of its richness has been aided in no small part by two great books, This Is Orson Welles by Orson Welles and Peter Bogdanovich, which contains a condensed version of the original script, and the BFI Film Classics monograph The Magnificent Ambersons by VF Perkins. The website Frequently Asked Questions About Orson Welles is well worth a look if you want to find out more about this film and the legends that have grown up around it.
Chicago Reader review:
Orson Welles's second completed feature (1942) and arguably his greatest film (partisans of Citizen Kane notwithstanding). By far his most personal creation, this lovingly crafted, hauntingly nostalgic portrait of a midwestern town losing its Victorian innocence to the machine age contains some of Welles's most beautiful and formidable imagery, not to mention his narration, a glorious expression of the pain of memory. A masterpiece in every way (but ignore the awkward ending the studio tacked on without Welles's approval).
