In reply to Blue Straggler:
> 2001: A Space Odyssey was MGM. The non-American-produced Kubricks still had US distribution fingers on them but I take your point gracefully. I hope you haven't missed MINE. No Malle, Godard, Wenders, Herzog, Rossellini, Murnau, Lang, Bergman....
This is a very tricky subject. Yes, as so often in movie history, most of the money for 2001, and the distribution, was American, yet it was based in a 'British' studio i.e. MGM Borehamwood (NOT the same as nearby Elstree Studios, nor BBC Elstree). Now, I haven't a clue how Borehamwood Studios (I think Gaumont previously??) were taken over by MGM/what the financial deal was, but it was surely a very big UK film production base, and actually called MGM British. Production company was v independent of MGM, being 'Stanley Kubrick Productions' and entirely UK Based. Certainly 2001 was nothing like a 'movie shot on location in England', and c 95 % of the crew were British too. As far as I know, nothing creative was done in America.
No, I haven't missed your point at all about all the other wonderful directors you name, most of whom should be near top of any best 100 list ... but sadly, almost none of them have ever been v mainstream in terms of British public. Always 'art cinema', sadly. The British public being mostly to blame for this, frankly.
