When I was a projectionist I loved being able to start the movie and see it all by myself. Usually very early thursday or friday I would be able to see what I want, and when you add to the fact that you'd be "checking" the movies for sound issues and or other reel/picture issues - meaning I got paid. Was a great college job.
When they re-released the exorcist my ex-gf and I woke up at about 2a.m. and started it up for just ourselves (I was a manager, along with being the head projectionist). It was very creepy to be in a completely dark buidling with no one when there are usually tons of people, but watching that movie with us alone (it was the first time watching it for both of us), man, that was an experience I won't forget soon.
