Does anyone know if white screens have always been used in theaters, and
"silver" screens are only used for 3D projection? ....or were all movie
screens once "silver"?

I've heard the term, "see the actor/actress on the silver screen..."
(referring to movie theaters)

It seems the term "silver screen" is synonymous with a movie theater.


Just curious :)
