Film
In February 2018, a feature film adaptation produced by Walt Disney Pictures was announced to be in development. The film is directed by Julia Hart, from a screenplay written by Kristin Hahn and stars Grace VanderWaal in the title role. Filming began on September 24, 2018 in New Mexico and wrapped November 16, 2018.[7] The film was released exclusively on the streaming service,[8] Disney+ on March 13, 2020.
While the plot remains relatively the same, various changes were made. Stargirl and Leo's relationship begins almost immediately in the film and they never formally break up, though it is slightly implied to be on Stargirl's part. Leo's fascination with porcupine ties comes from his deceased father rather than his uncle who is never mentioned. While Kevin and Dori are included, with the former's last name changed from Quinlant to Singh to match with the actor's ethnicity, various new characters are added as part of Leo and Stargirl's social group. Hillari's role is somewhat reduced, however she is still responsible for Stargirl's sadness. Rather than a typical bully, Hillari's dislike for Stargirl comes from how she inconsiderately tried to cheer up her brother, only to make him more miserable. Stargirl apologizes to her at the end. There is also heavy emphasis on music in the film with classic rock songs being used. For the dance at the end, instead of Stargirl leading everyone into the "Bunny Hop", she has Leo perform "Just What I Needed" by The Cars.
