H&H supplies Hollywood with filters. The US
cinematographers do not like coated filters for
reasons which remain a bit obscure: perhaps it
is just a matter of tradition. They were quite
slow to adopt coated lenses and only did so when
Kilfitt supplied most of the non-standard stuff
in the 1960's and 1970's and simply refused to do
special runs of uncoated lenses.

I would like to know the source for thisstatment. TT&H
supplied most of the lenses used in Hollywood from about the
early 1930s until Bausch & Lomb began to make the Baltar
series about 1950. AFAIK, all the B&L lenses were coated and
those made by TT&H after WW-2 seem to have been coated.
TT&H made coated lenses for Technicolor for use on their
three-color cameras and also for projection from the mid
1930s when the three color version of the process
originated. _When Gone With The Wind_ was first released
Technicolor sent coated projection lenses to theaters for
use in showing the film. There was a handbook of
instructions for setting up the theater sent around with the
movie. It specifies the threater lighting and projection
techniques. The Motion Picture Academy has a copy and there
may even be one on line. In any case, I've never heard that
Hollywood was conservative about lenses although everything
was pretty thorougly tested before using it on features.
Many D.P.s had their own collection of special lenses. Its
possible some D.P.s may have not have liked coated lenses
but in general they seem to have been pretty standard by
about 1950.
BTW, one of the early experimenters with lens coating was
Radio Corporation of America. They were interested in the
use of coated lenses for photographic sound recording and
possibly also for optical printers. The research at RCA
appears to have begun in the mid 1930's.
