Interesting point about his version of the Odessa Steps. I've never looked at it that closely and so always took it to be quite faithful to the original. Ultimately though, like your thing with Carrie (which is actually very good, btw) I don't particularly care because I don't think The Untouchables is that interesting a film anyway or DePalma that interesting a filmmaker. And I can never decide whether Scarface is a really good film or a pretty bad one that just happens to be really enjoyable.
Anyway following the discussion of Bava, I just watched a erm Roger Vadim film ...
Barbarella
If nothing else, I suppose it's definitely one of the most 'sixties' films out there but where say Danger Diabolik is simply too well made to be written off simply as a kitsch historical artefact of swinging Europe, I'd say that's pretty much the sum of Barbarella's appeal these days. The film equivalent of a lava lamp.
