Well, I'm in pre right now. We got our budget from the line producer and are going into casting.

Fortunately one of the first things I learned was outlining so the director wants to - can - film it "as-is" since I NEVER TOUCH FINAL DRAFT UNTIL I CAN WRITE OUT 60 or so sequences in outline and hit the marks I'm aiming for.
You can also - as he said - avoid rewrites by saying the lines as well-acted as you can.

What I found in our budget was that we have NO SPECIFIC props, just rooms with furniture.

If you're writing low budget, the considerations are LOGIC, LOGISTICS and LOCATION.

LOGIC: A space movie won't be cheap.

LOGISTICS: How do we get the camera in that small space?

LOCATION: Do we really need two apartments or just extra furniture?

I use those three elements to determine everything even if I write for an unlimited budget. Someone does have to film what you write.

Great advice: "LOGIC, LOGISTICS, LOCATION." That should be something that's up on any independent filmmakers wall. Probably any filmmaker period, but indie guys/girls especially.

Congrats on going forward on the project, too! What's the budget on that? And if you found an investor, what in gods name did you do to get that money?
