2. The scene that made Lana extremely emotional while filming was when Lara Jean walks down the stairs in her dress — she said, "It was like my Asian Cinderella moment."
3. While filming P.S. I Still Love You, Jordan Fisher organized a ton of game nights and movie nights for the entire cast so they could bond off-screen.
4. For the chemistry read while casting John Ambrose, Lana read the bingo scene and the scene when Lara Jean and John Ambrose dance at the ball with the other actors.

10. While writing the book version of To All the Boys I've Loved Before, the first letter Jenny Han wrote was actually John Ambrose's — one of the reasons she ended up writing P.S. I Still Love You is because she loved his character.
11. Costume designer Lorraine Carson heightened Lara Jean's fashion for P.S. I Still Love You. Her outfits now feature custom-made headbands and more vintage-inspired pieces.
