If you landed here searching "how to make short films," you've come to the right place. Unfortunately, it's hard to answer that question in one posting (this whole blog can be seen as an explanation on how to (or how NOT to) make short films.) But, I'll give it a shot.
First, read Mike Figgis's
Digital Filmmaking and/or Robert Rodriguez's
Rebel Without a Crew. Both those books will make you say, "Hell, if I want to make a movie, I need to just do it!" That's the spirit. Keep that energy. You'll need it.
After you've got the motivation, write a short script. Use MS Word if you don't have screenwriting software. You might want to set your short in places you know you can film, don't have any stunts or blood or anything that might be complicated. Limitations spawn creativity. Seriously. (Proof: Write a short about life. Then write one about your favorite cup. Which was easier to write?)
Next, get the actors. Hopefully they'll be good, and hopefully you'll get along with them.
And finally, shoot the damn thing. I know what you're thinking, what about sound, lighting, camera angles, and everything else? Who do I get to cater?
This is your first short, right? Got a camera? Just start shooting. It ain't gonna be pretty the first few times, so just get them under your belt. You can be creative in the editing room.
Which reminds me: edit your short well. Do it yourself. Take your time. Put in music, sounds, etc. Use iMovie or Final Cut Pro (any version). It all happens in the editing room.
Hope that helps! We've made thirteen short films so far. Thirty-nine to go. This advice might all change by the time this project is over.
But until then...write, rehearse, shoot. And send us your youtube link. We like to watch them too.
