The ending song could've been "Landslide" by Stevie Nicks. But seeing how "Prom" had so much impact in Gio and Joanne's love story, Jadaone decided the latter would be the better song to end the film.
Gio's and Joanne's "Ikaw at Ako" and "You and Me" tattoos were the real handwriting of Reid and Lustre.
Norman King, the first Aeta graduate from the University of the Philippines, was Lustre's Zambal coach.
The film was shot in the Philippines and has several scenes in London.
Nadine Lustre chose "love" as Gio and Joanne's term of endearment.
