Luminance of movie theater projection screen

I took my faithful Minolta CS-100 along tonight to see a movie at the local
Famous Player theater and I was shocked to find luminances no higher than
20
cd/m2 in the brightest part of the projected movie.

The cinema manager told me once they are using powerful Xenon lamps in
their
projector which cost them an arm and leg.

But I was expecting much higher luminances than what I measured tonight.

I suspected my CS-100 calibration could be completely off. But I don't see
how it could be so off.

In comparison, my 30" Samsung CRT TV set produces 115 cd/m2.

My Eizo CG21 LCD measures 100 cd/2 (I calibrate it that way).

I can't believe that Holywood movies are viewed in so little luminance in
commercial theaters.

I wonder if Hunt writes about luminance in movie theaters in Color
Reproduction?
