At one time there were several marketing firms that maintained
"mailing lists" to distribute free/promotional movie theatre passes. 
These were generally done to get people to fill up pre-release shows
and parties
and to help 'generate buzz' before the official release of the movie,
usually at a special screening.  Is this service still available and
how does on go about getting on a list for movie releases in the state
of Minnesota?
