Pre-movie "Be polite" videos and coke commercial clips
I was wondering if anyone knew if there is anywhere to obtain pre-movie videos like the ones Cinemark and other chains run before a movie to "Be polite", or dolby clips, or the coke commercials and such. Not that I expect anyone to be rude, but I just thought it'd be cool to have those as part of the atmosphere. Vintage concession stand ones would be cool too.
I've done a lot of googling and it's been pretty hit or miss, so I thought I'd ask here.
