When you’re busy making your film, it can feel impossible to stay on top of grant deadlines and opportunities, festivals, and general industry goings-on. But knowing about these things can be essential to completing and distributing your film. Thus, a line I never thought I’d compose: thank goodness for Twitter. These accounts can help you keep track of what you might need to know outside of the edit room. (And, shameless plug: you can get a lot of this news on our Indie Film Weekly podcast every Thursday morning, too!)

The folks that brought us The Good Pitch fill their feed with useful tidbits for doc-makers, including a list of 100+ funding opportunities.

Firelight Media - @firelightmedia
Not only does Firelight make films, they also fund and run fellowships and labs for other makers. An all-around resource.

A screening series run by New York’s documentary guru Thom Powers, their Twitter account links to additional news, like their “Monday Memos” which round up the week’s happenings from all over the doc world.
