Let's make a short list of what one needs for a successful campaign without going to deep into the details:
- pervious work to show you can do it
- an engaging video to persuade people to share or donate
- an engaging text that's clear about the project and expenses
- clarity about cast, crew, script, etc
- a fanbase and/or mailinglist of people to contact directly or even before the campaign
- news articles to send to (local) newspapers at the start and later during the campaign
- a seeding strategy to reach out to your target audience on internet(fora) and drive traffic to the campaign
- social media profiles on facebook & twitter to get the news out and to make sharing easy
- plans to send out more news and updates during the campaign
- good ROI and / or rewards for funders with a healthy margin to use for the project
- stamina
