Actually I'm using just 2 light sources: the projector lamp itself (with 
some really high intensity: rgb 125000) and a quite dim one within the 
projector cabin.
The scene illumination relies completely on GI and comes almost 
completely (there might be some minor radiosity-media interaction from 
the light-beam with the 'dust') from the screen where I did *not* use an 
image_map but instead the light from the projector is projected_through 
a small image with filter value set to 1 and located within the 
projector - kinda like the real thing.
The only *fake* is the skin of the kid that has its own light_group with 
a few reddish colored lights (kinda SSLT fake) to get a skin tone that 
does not look too natural but also does not look like plastic - to make 
it work with his cartoonish style.
But this is not so much *fake* at all because I'm pretty sure when such 
a shot is done for a *real* movie they would at additional spots and 
reflectors - lots of them ;)

Well, perhaps this volume light from the "dust in the air" is quite a 

still used because it simply helps in making this movie theater flair?
Yesterday I did see "Unknown Identity" in the theater and did actually 
watch out for the beam - but it was too faint to be visible.

Hum, well, hopefully we do not make our favorite render engine look too 
bad among all this Maya, Mudbox and what not 'big boys' tools...
