This was the era when movie lettering was still hand lettered rather than transferred direct from a font.
Looks like a version of the widely used Trajan column letters.
Update
The _E_ is wider than usual for a classical Trajan.
I agree that the letters have a Tuscan flavor with the bifurcated ends, but off hand I don't recall a Tuscan that is an exact match.
In these letters the bifurcated terminals are very restrained compared to the digital fonts that I have seen.

I found something that might work as a substitute.
It is a design made many years after the move -- in 1991-- by Richard Lipton "based on Lipton’s own hand-lettered calligraphic alphabets that draw their influence from classic inscriptional forms." Check the terminal treatment on Arrus BT Roman https://www.myfonts.com/fonts/bitstream/arrus/
The serifs extend too far and the weight is too heavy but it has some of the flavor of the lettering.
Don

That lettering immediately brought to mind Artcraft,

Artcraft has the _T_ and _E_ with top serifs blowing in the wind, a feature that's missing from Arrus, which is in most respects the closest match. Can we think of any other similarly windblown serif fonts?

Edited
I reserved the film fom my local public library and should be able to view it within several weeks.
Is there any more lettering in this style?
Don

Thanks Don,

It'd exactly the subtlety of the terminals that I rather like.

Arrus is an interesting one.

From what I can remember there is another heavier variation and (a rather unpleasent) one with a slightly celtic feel, but I think this is the only text in this lighter variation.

Pedr, Arrus is part way there. But to get these letters you really have to create them from scratch. Arrus is good in that it gives some idea of how to make some of the terminals. Draw on this and the windswept top terminals from Artcraft and it is possible to create something similar. Fair amount of work.
I think I saw the move many years ago and enjoyed it. Good stuff without Hollywood mega funding. Look forward to when I can see it.

Actually, I just noticed that good ol' Centaur - albeit sharper - has similarities.

Don - another "windblown" face is Worcester.

Thanks Mike, for the two windbown faces. Worcester is really in a heavy blast.
I expect that the lettering artist could have seen Centaur and this may have influenced the lettering.
Don

The pangram for Worcester on MyFonts is 'When the zephyrs blow'.

Thanks Pedr. Coincidence or subtle description?
