(Those of you who've seen it, anyway...)
I just bought the restored version on DVD (before that, I just had a cheap VHS tape with a scratchy, crappy print).
It's not my favourite Welles film, but I've always had an affection for it. Welles insisted that it was one of his best works, and it's one of the few that was actually released in the form he intended. And really, was anybody ever a better choice to play Joseph K than Anthony Perkins? I think not.
I've never cared for the weird ending, which has absolutely nothing to do with Kafka's intentions, but other than that it's such a visual feast of bizarre, surreal images and vignettes that I can't take my eyes off it (as with a lot of Welles movies).
Now, if only somebody could restore Chimes at Midnight and sell me the DVD... that would make me very happy.
