I've mentioned before that I'm taking a class in advanced screen writing at Pittsburgh Filmmakers. Last week's assignment involved an exercise that might prove useful to any writer, no matter what you're trying to produce.
The exercise is this: Write 25 pages. Now.
Sounds a bit impossible, doesn't it? I mean, it's daunting to look at that blank screen staring back at you.
How can you fill it even once?
There is only one way. Sit down and write.
Keep on writing. It doesn't have to be perfect. It doesn't even have to be good. There will be time for revisions later, time to correct those spelling errors and shuffle those scenes. For now, the idea is to get into the creative flow. The words will come. The ideas will come. Trust me.
