I love production but it is physically and mentally tiring. If your the director have an answer for everything but be willing to alter your plans and take good advise and ideas. Keep your team apart of the project, fed, shower them with praise and you just might make it. And plan on rain, it just happens that way.
See the guy on the left, he doesn't look as freaked out. That is how you need to be, smile and work through it. Good luck!!
**TIP**
Honestly buy duct tape and several cans of spray paint. Stuff just breaks, have a way to fix it enough to keep moving. One of our actors Jay was a pro at fixing broken guns on set, the guy was a craftsman with spray paint.
**STORY**
You do plan for everything to go wrong and it goes wrong in ways you could never image. All sorts of shenanigans happened on set, it did rain, a gun was broken before the first shot was popped off, we broke 5 of the 6 AK47s in the first scene, we got kicked off the neighbor's land a day early *cough cough*, half the set was falling apart because of the rain, and a million other things. I know i am repeating myself, but you have to be calm and just fix things.
