You're on one of the middle rungs of the power ladder on a film set. You do get to order around your mic operators and other lowly technicians, but at the same time you have to answer to the AD, director, and producer. You're basically like that middle Russian nesting doll. You know—those dolls that fit one inside of another? Right, just like one of those.
Regardless of the chain of authority though, you have a part in creating movie magic, and the projects you work on will entertain, amuse, and inspire. There's a lot of power in that. You can even carry around a scepter if you want, although it probably won't do anything.
