Shoot everything in one location.
How? Why?
- Everyone is locked in the house.
- Everyone is locked out of the house.
- Everyone is waiting in the house for the thing to arrive.
- The house is where the treasure is.
Or perhaps:
- There's a break-up (remember that episode when Ross & Rachel spent the whole time breaking up in Monica's apartment?)
- It's the rendezvous point (remember 'Reservoir Dogs'?)
- It's the place to muse about life (Reminds me of a great episode of 'One Foot In The Grave', where Victor spent the whole time in a Doctor's waiting room)
- They're stuck there (Saw? Big Brother?)
You can't afford a big beautiful HD camera to film it on?
Film it on your video phone:
- The world is about to end, there's a poisonous gas outside, and you video it for evidence.
- The film is about someone secretly filming someone in a house.
- It's a video of someone doing an audition via their iPhone, when suddenly; horror-type-things-happen, or there's an argument, or an unwelcome visitor.
Film it on your Dad's old video camera:
- It's a rare-look-what-we-found-footage-film (Cloverfield, Blair Witch Project, The Troll Hunter)
- It's made to look like old camcorder footage (a film about memories, or a dead person, perhaps)
- It's a YouTube style sketch.
- It's a documentary/mockumentary
"Perhaps it sounds ridiculous, but the best thing that young filmmakers should do is to get hold of a camera and some film and make a movie of any kind at all."
-Stanley Kubrick
