Pan shots

[Jason Gray]

Hitchcock deliberately employed right-left pans (or
tracking shots). In "Vertigo" and "Rear Window", I
believe. As for the broken POV, I don't know why I
remember, but the indie film "Palookaville" (a take off on
"Big Deal on Madonna Street") had a great example of it.

I don't know about any cultural aspect, but as the word
"grammar" evokes rules, the studios may have told their
trainees that right-left movement was "wrong", not unlike
crossing the line of action or cutting to a closeup
without changing the angle, etc. The filmmaking was
supposed to be "invisible" in mainstream entertainment,
and somehow a right-left pan wasn't. Suzuki broke too many
"rules" (fascinatingly) and was kicked out of Nikkatsu for
it (and what is the best account (Japanese lang. okay) of
that whole period, by the way?).
