If you have large theaters - say 24 screens - you really need a relationship with theater management. They are always short staffed and busy, and they have to tell you which prints are on which screens. No matter what the MSC tells you, there is absolutely no way to figure this out in a large theater that splits screens throughout the day/evening. Popular movies may have several prints (2D, 3D, etc.) moved around on different screens, and you don't want to waste time watching the same print twice. And you are not being paid enough to spend an entire day/evening watching trailers. If you have first show time checks, most prints will be the first show time on a screen (say 11 a.m.). But, on a split screen, one first show time print may not be scheduled until 10 p.m. And then factor in all of your reporting. This time of year is crazy with all the new films. Good money when it was paid per screen. Less money, more work now.
