Ve filmu Rivalové od vizionářského režiséra Luca Guadagnina hraje Zendaya roli Tashi Duncanové, bývalé tenisové šampionky, která se stala trenérkou, jež se neštítí své hry na kurtu ani mimo něj.
Rivals, from visionary director Luca Guadagnino, stars Zendaya as Tashi Duncan, a former tennis champion turned coach who doesn't shy away from her game on and off the court. Married to a champion near the end of his career (Mike Faist - West Side Story), Tashia's strategy for her husband's redemption takes a surprising turn when she has to confront the washed-up Patrick (Josh O'Connor - The Crown series) - her former best friend and To Tashi's ex-boyfriend. As their past and present collide and tensions rise, Tashi must ask herself what victory will cost.
