Carley: I think show Charlie and book Charlie are so similar. When we were filming Every Year After, One Golden Summer had come out. That book is about Charlie, and Michael [Bradway] was reading it while we were shooting.

Charlie is a character who has so much going on beneath the surface. He’s very funny, and people sometimes assume there’s less depth there than there really is, but that’s actually how he’s learned to protect himself.

Amy is an incredibly empathetic writer, and she really understood Charlie. We talked a lot about what it was like for him being the older brother when their father died. That loss landed on him differently than it did for Sam, and he felt a responsibility to keep things light.

One of my favorite parts of the adaptation is that we have access to the brothers in a way that we don’t in the book, but it feels so true to Charlie and Sam. We get to be there when Percy’s not there.

Charlie has always been a character I thought about a lot. After I finished writing Every Summer After, even before I had a book deal, I started writing from Charlie’s point of view because he’s the easiest character for me to write. Out of all my characters, he comes to me so naturally. I think Amy found the seeds of all that and brought them to life beautifully. 

She really set us up for what Charlie’s story could be in a second season. I really, really cannot wait — knock on wood — for a second season.
