Old film via image_map:

   #declare vintage_amount=0.9;
   #declare f_old_film=
   function{
     pigment{
       image_map{jpeg "old-film"}
     }
   }
   tonemapping{
     parameters{red,green,blue,x,y}
 
function(r,g,b,x,y){r*(1-vintage_amount)+r*f_old_film(x,y,0).red*vintage_amount}
 
function(r,g,b,x,y){g*(1-vintage_amount)+g*f_old_film(x,y,0).green*vintage_amount}
 
function(r,g,b,x,y){b*(1-vintage_amount)+b*f_old_film(x,y,0).blue*vintage_amount}
   }

Let the art connaisseur praise the artist, and leave it up to the artist

Everyone have fun & enjoy!

   Thanks to both. The nice "old film" image map is a frame from a
footage by cutestockfootage.com.

This is indeed amazing. (I'm dreaming of an animation where the hair on 
the film moves).

But ... who keeps a wooden hourglass on a concrete floor??
