“With an adaptation, you can never give back your first read. So, what are you taking away? What fills your soul? Why do you want to tell this story? And then that becomes sort of the North Star. And I’m tethered more by that North Star than by the actual moves that are happening in the book,” says Long Bright River showrunner, Nikki Toscano, about adapting Liz Moore’s best-selling novel for television. 

Long Bright River is an emotional suspense thriller that follows Mickey (Amanda Seyfried), a police officer in a Philadelphia neighborhood hit hard by the opioid epidemic. As a string of murders unfolds, Mickey must find her missing sister who’s also battling addiction before it’s too late – but long buried family secrets stand in the way. 

On the surface, the show is a highly engaging murder-mystery, but beneath the whodunnit is a love story between two sisters. We chat with Toscano about delving into the sisterly dynamic that is both compassionate and toxic at the same time. 

Toscano shares tools for building an enticing mystery that includes giving your characters secrets to help drive the story. 

“I think that in the beginning of anything, you have to determine what your character wants and then put a bunch of people or things in that character’s way. So that’s how secrets are born, right? And that’s how you have your audience leaning in. Is the secret going to come out? Who’s going to tell the secret? You and I could be having a conversation and I say, ‘Don’t tell anybody!’ And then the next scene is you being in a situation where do you tell, do you not tell? It’s about setting up those kinds of things. I mean, whenever building any kind of show, whether it’s an adaptation or not, determine what your character wants and then stick a bunch of people between them and that goal that either complement or compromise your character’s journey,” says Toscano.
