No.  Larger budget films shoot on 35mm.  Smaller budget films were shot
on things like super 16, but now are increasingly video.  Some release
prints are 70mm, although that obviously requires appropriate
projection, but films shot on 70mm throughout are vanishingly rare, and
I think only two or three were shot on 70mm throughout the 90s.  You can
get an idea of the sort of things that were shot that sort of stock by
looking at:

The problem, of course, is that the cost of the film is frightening and
the size and cost of the lenses and cameras are massively increased.

Anamorphic lenses aren't about compression between formats, they're
about getting a wider image onto the standard frame.
