Very avant-garde! Some Brakhage and other avant-garde films, including Anticipation of the Night (which i've not seen), have finally become available on dvd/video in Britain, but my usual source are only selling not renting them. I'm tempted but it could be an expensive risk! I'll try some persuasion over rental, first.
The General; i presume it's the Keaton masterpiece on your list, (not the Boorman). Anyway, a good chance to plug it as Brecon film society (Wales)' next screening on 7th April. With live, specially composed musical accompaniment- promises to be a grand entertainment. Our resident composer gets to know these silent films very intimately (in fact better than anyone), as he's a perfectionist about timing the score to fit the images and mood- which certainly isn't the case with many others i've come across. All too often the music on video/dvd for silent films feels like it could have been written for any film. Lazy!
The Band Wagon just missd out on my 20, but it really is wonderful. The second half, the extended Girl Hunt sequence and the closing speech by Cyd Charisse (which always has me gulping- good old Fred) in particular. It just pips Singin in the Rain, imo.
