Trailer names are the easiest part of a movie assignment.
I have met two other people who do movie assignments. One of them told me that she gathers a team and they sign up for several movies at the same theater at the same time. Then they parcel out the times so each of them gets to see a different movie each time. I can't imagine how that works. I've never even seen more than one assignment even at the largest theaters. They also must have a special agreement with the company to allow a different person for each showing.
Once, over two weekends at a small theater, I saw parts (Because I was working, I couldn't pay attention to the movie all the time.) of the same movie 18 times. After that many times, I found out what the actors were really saying when they mumbled. At least it wasn't a movie that I couldn't stand.
