ok thx i have a 5 $ a mouth bugget and my costume not finished and what wood did you use for your br85hb battle rifle
At five bucks a month, at best you're gonna be saving a while and paying cast and crew in pizza. What camera, lighting and sound abilities do you have? You can shoot with an iPhone on a piece of wood and some china balls if that's all you have available, but sound is more critical than people think- gotta have an external mic if you have people talking, no matter what you're shooting with, unless you have some way of really cleaning it up well. What about post? Editing, music and CG? Who do you know has a workstation or sweet gaming rig that can run some decent software? And that's just the gear itself.
Crew-wise, you'll need someone to run the camera(s) (might be you), someone to hold the mic and run the recorder if you have one (sometimes the same person as the camera guy, but preferably not), a director who keeps everyone working in the same direction (that might also be you), a writer (obviously; might also be you), preferably a script supervisor- a person who takes down notes on blocking, wardrobe, etc to maintain continuity, and probably one or two other miscellaneous positions like a gaffer and a wardrobe/hair/make-up artist, or something.
Cast-wise, it depends on your story concept. If it's man vs. nature, you could have a single actor. If not, you're probably at least going to need one protagonist and one antagonist. Maybe with some quick and cheap cardboard costumes and a wide enough lens to hide the crappy costumes, you could do some larger battle scenes with extras.
While yes, it is possible- with a good enough script- to pare this down to you with a phone, a household lamp and your actor, a film- short or feature- is a far bigger undertaking than most people realise.
You may even need to trade on favours for skills, it might require you to do some stuff you don't wanna do- do your friends' chore lists for them in return for their work time, maybe. Not all your friends might be available, or skilled in something useful to the project, so you may have to look further afield. Your school's drama people, or theatre crew, maybe. They may have AV gear- can you beg it from Media Studies or whoever has some camera gear, maybe? Dunno if Canadia does the weird militarised school thing like here in the US, but do you maybe have a ROTC or similar program that you could borrow kids with actual military skills.
TLDR:
1) it's gonna be difficult if you want to do it well. Don't delude yourself or your friends on that. Save up some money first to help (warm food kills tensions quick).
2) Think outside the box- in this case, your circle of friends- on who might have skills useful to you, and find ways of making it worth their time.
3) Only once you have a list of available talent and resources can you actually start figuring out what story you can tell with them.
PS. My BR85 is made from MDF, styrene and Bondo. For this project you'd be better off going with foam.
