no, it was not polarizing film per say. It was the 3m dual brightness film i had (not the thinker stif kind, but the flimsey thin stuff) which in a way is polarizing film since it make light go only stright. My goal for hte summer is to buy some different types of polarizing solutions and try them all. Maybe one of those glass polarizers that could be place near the light source.
Finally off moderation!! 
Verbose,
Is this the stuff you're talking about?

I did a quick read over the PDFs and product information and while not an expert.. the purpose of the films is to increase brightness for LCD panels.. but no idea how they work with out 1000w light bulbs half a foot away. The PDF has a little section about how it'll warp etc under heat so keeping it as cool as possible is still preferable.
There are also different angle versions of the films.. 0degree and 45 degree.. what would the differences be?
This could be an exciting find for everyone 🙂

hmmmmm..why would you wanna make 119,000 lumens brighter? half a foot...?? hehe i think your gonna REALLY make ur LCD liquid...
just IMO...

sadd3j, that is the stuff. We found it here a while back and a bunch of people contacted 3m about free samples. I emaield them and the samples arrived at my door in 2 days. The film is made to be placed in an lcd montior between the back light and lcd. What it does it lets light going at a 0 degree angle go through, and reflects light going at any other angle untill it too goes stright. So instead of being able to view you lcd monitor at muiltiangles, you will now be about to only see it head on, but in turn it will be up to twice as bright. This stuff really does not do much for a big metal halide lamp, but it does (as you talked about from the pdf) capture the heat while polarizing the light. Im currently running my ohp, and day, its like a sunny day in here 😀. Im trying to find the best place to stick this film (IE, bewtween the fresnel, stageglass etc. I'm very exited to buy some different types up polarization films to see which works better.
