Making [Spoiler] in The Summer I Turned Pretty Boss Changes in sexuality in book-to-television adaptations The character of Jeremiah Fisher (played by Gavin Casalegno), one of two brothers fighting for the love of 16-year-old Isabel “Belly” Conklin, is one of the most significant alterations in The Summer I Turned Pretty’s shift from novel to TV series (Lola Tung).
In comparison to his book counterpart, Jeremiah is sexually flexible in Amazon Prime Video YA drama (which debuted all seven episodes on Friday). He lists all the females and boys he’s kissed at the country club in Episode 2, then subsequently portrays himself as an equal opportunity flirt.

“My approach to this adaptation was to think about how I would convey the narrative in the year 2022.” What would that entail? “How would that affect things?” says the narrator. Jenny Han, co-showrunner and author of the novels, tells TVLine. “I believe I would have made that choice if I were writing the novel today because he’s always been a character to me who is at home with himself, comfortable in his own skin, and openminded and open to discovery.” That, I believe, is more indicative of today’s youth and the way they approach sexuality, which is much more of a spectrum.”
