When filming, they place markers on the floor where the person is supposed to stand. IDK if that's what that is.. but we put tape or these little sandbag type things. (I know.. but I didn't know about Nike at that time and yes, I stopped acting because the casting couch was a 'Hell no! Go fuck yourself AND your script!!!' for me..) No tit pics either cuz I'm a good girl. I don't have any, anyway but… kmao. Sheeeeet..
(In this student film, I was an actress in my dressing room after starring in a play. It wasn't anything naughty.. I'm in my robe the whole scene. Just so y'all know it's a clean scene. Dude came to leave the character I was playing, pregnant, and run off to marry some other girl. Kek. Scene ends with him leaving and me crying.) Yes acting is gay and I can't stand hollywood and all this shit nao. But I quit long ago. God saved me. POINT IS.. they use markers on the floor when filming, so it could be that.
