Most of my film ideas, started off with something that happened in real life. My "trapped astronauts" movie,
TERRARIUM was inspired by taking care of a friend's tarantula, for 6 months. I would put the crickets in the terrarium and then I would think to myself, "what if those crickets were people?" The idea was born.
For my movie,
ROADKILL, my inspiration came from a fight with an ex-girlfriend. She was yelling at me, so I just got in my Trans am and started backing out. While the car was moving, she scratched my neck and didn't let go, so I gave it some gas.
Anyway, she couldn't hang on, but I thought what if she did? I made the movie around the "What if?"
I also listen to movie soundtracks, so I get lost in that dream mode and think of all sorts of ideas. But,.........and this is a huge "but", nothing inspires me more than watching a no budget indie movie that becomes successful. Specifically, it was a Super 8 movie, called GAME OF SURVIVAL, which was all over the place, when it got released in the 80's. At that time, there was also A POLISH VAMPIRE IN BURBANK, also shot on Super 8, which did huge business. Of course, EL MARIACHI came out and that is the poster child for the indie success story. Still, everytime a BLAIR WITCH, FIREWALL, OPEN WATER or anything along those lines catches fire, I'm totally inspired. I watched Peter Jackson go from BAD TASTE to where he is now. When I get the inpiration, story ideas just flow....
When ideas are dry, I'll drive out to some weird desert locale, put on a soundtrack, or watch something I know nothing about. Sometimes, it takes 10 movies, before you get to the inpiring one, but we're filmmakers, dammit. We should be watching all sorts of unknown material, and not just what the critics and masses say are good.
