What is an Organized Festival Submissions Spreadsheet?
At this point you should have a list of all the festivals you want to submit to ranging from the top tier fest to the local ones. Using a spreadsheet is most helpful as you'll want the country, date of the festival, the month it falls under and whether or not its a pass as well as tracking where the materials are. It should look something like this.
You should have one for each year of your festival circuit which should last about two years per film. This way if you happen to bump into a programmer at another festival where they are still deciding, you can talk about your film in person.
