Lesson # 4: Multiply all movie-related numerical estimates by six.
So you think you’ve written a foolproof budget? You’ve counted out how many hours you’ll need for your editor – and you’ve even been liberal and thrown in an extra four weeks. Just in case. And, on top of all that, you’ve added 10% of your budget to your total for “contingency costs” – you know, for all those expenses you can’t foresee.
Now, take your total figure, multiply it by six, and you’ll get what your movie will actually cost.
And time?
1 (year) X 6 = six years
Arithmetic for documentary filmmakers is really that simple.
