Revision! Revision! Revision!

Writing a film treatment is hard work. Jose and I are writing a a noir film called, A Table Twice Turned. We're on our third revision of the treatment. This time, our story is changing nearly completely. Characters are being changed, new problems are added to the movie, and a lot of the core elements of the film at being removed.
The only problem I have is thinking of more to write. Writers block is hitting me hard. Trying to make every element work is hard. Imagine the story like two puzzles thrown into a pile an mixed. It's our job to find, fix and combine the pieces for us to finish the job.
