Cinematography

Very true! However, it looks like they are using (or had to use) early-generation anamorphic lenses. You can tell by the warping on the sides. As figures move toward the edges of the screen, they become compressed. There is a panning crowd shot earlier on where it is most evident.

You usually saw this in the early Cinemascope lenses of the mid-1950's. After that, though, later-generation lenses lessened that effect. But, in 1964, it appears that they might have been using these older lenses. Budget restrictions, perhaps.

It's a gorgeous looking film.
