Late night error, thank you for pointing that out. European etc PAL formats go sharp when transcribed to. So American and all films transcribed into PAL go sharp, which happens a lot. So it's not the origin of the film, but the (usually) PAL format I historically watched them in that caused this.

And in cinema they were better (I seem to remember Geoffrey Rush 'playing' Rachmaninov 3rd Piano Concerto in that film, at excellent pitch in the cinema), so I knew they were sometimes right. But i think the tape, TV and DVD formats I'll have rewound most often in perplexity.

Another confounding: living in California a lot and not having incorrect pitch on local copies. And nowadays, when sources are digital, bit may have originated from analogue recordings, it's now very unclear what to expect.
