Okay, plain and simple, people in film are nuts! Who else would get up at 4 am stand around in heat and glaring sun dressed in heavy clothes and come home at 1230 am the next day and think it normal?  Alright, maybe it's just me who's nuts; Call at 730 am drive time 2 hours, on set until 1030 pm, home by 1230. But what gets me is that the crew is there earlier and stays later! Hat's off to "the crew" of any film set you guys are amazing!
