If you're thinking a The Summer I Turned Pretty movie or show prequel featuring Laurel and Susannah's friendship origin story sounds intriguing… well, you're not alone. Blanchard even has an idea for who could play young Susannah: Maddie Ziegler. As Laurel and Susannah, these two actors form the bedrock for all the drama and childhood nostalgia that Belly, Conrad, Jeremiah, and Steven go on to experience at Cousins Beach. Their friendship chemistry is crucial; the more self-serious, grounded Laurel is balanced by the effervescent, party-planning Susannah, and vice versa. It’s possible we might even get more backstory in the Summer I Turned Pretty movie.
