The Sun Is Also a Star: The biggest changes from book to screen
The Sun Is Also a Star tells the love story of Natasha and Daniel, played by Grown-ish's Yara Shahidi and Riverdale star Charles Melton, two teens who meet at a critical time in both of their lives and fall for each other in a matter of hours. The film is based on the 2016 book of the same name by Nicola Yoon, and, as with any adaptation, there are some differences between the movie and its original source material.
Let's break down the biggest differences between the film and the book:
In the book, Natasha is trying to stop her family from being deported "today," whereas, in the film, they're being deported "tomorrow." Essentially, in the book, Natasha and Daniel fall in love over the course of about 12 hours as opposed to 24. That also means that the sleepover in the park was not part of the book.
Although the big heroic moment of Daniel saving Natasha from being hit by a car happens in both the book and the film, the book has the two of them already talking before that moment. Before he saves her life, Daniel follows Natasha into a record store where the two talk, and Daniel introduces himself. He also busts her ex-boyfriend for stealing. The save then comes after that interaction. In the movie, Daniel sees Natasha in the crowd at Grand Central Terminal, but they don't speak until the big save.
The karaoke scene
In the film, Daniel sings "Crimson and Clover" by Tommy James and the Shondells when he takes Natasha to Korean karaoke, but, in the book, he chooses another song — or, rather, lets another song choose him: "Take a Chance on Me" by ABBA. Additionally, in the book, Natasha takes a turn behind the mic and sings "Fell on Black Days" by Soundgarden.
In the film, five years go by before Natasha finds her way back to New York and deliberately tracks down Daniel at the coffee shop they went to together and they kiss. In the book, 10 years go by before fate brings the two of them back together: They're both seated on an airplane when Daniel recognizes Natasha's voice. The book doesn't end with a kiss, but, rather, Natasha saying: "Daniel."
