Lessons from this screenwriting gig

Adaptation Lab I’ve been on with the CFC and EOne for the past six months. I think they are making me a better writer in all my writing endeavours and I want to share some of that edification here.
Scenes need to do more than one thing. They need to move the case forward of course, but they should also reveal things about your characters as they progress through their arc for the episode. Also, if you can subtly share things about your ‘world’ in a scene, for example, “Portia is overwhelmed by the bread line as it wound its way around the block,” puts you in the Great Depression better than explicitly saying it.
Scenes should end with a question. I would extend that to chapters in books because ending a chapter with a question gives the reader a reason to ‘turn the page.’
Bring up the themes again and again in new ways. Unlike books, I find writing for TV requires more themes that parallel each other through different characters in the show. So yes, Portia is an outsider, but her clients are outsiders as well, and there are lots of reminders of her ‘outsider-ness’ throughout the episode.
Minimize the number of characters and differentiate their names. Unlike books where if you forget who someone is you can go back a few pages and remind yourself, once the episode starts, you’re rolling along and your audience doesn’t want to rewind. This isn’t a hard and fast rule, but I’ve received it as a note a few times.
