Seriously. They suck you into their filmmaker vortex and before you know it, you agree to help them with their "labor of love".
Tomorrow morning my alarm clock is going to go off at 5am. I am supposed to be "on set" by 6am.
Am I starring in this film? No. Do I have a lot of lines? No. I'm part of an angry mob of women.
I now have to go to bed.
In conclusion, stay away from filmmakers. Or, at the very least, if they ask an innocuous-seeming question like, "Hey, what are you doing next weekend?", lie. Say your busy. It's a loaded question. They're trying to manipulate you into helping on their film.
Again, going to bed.
