Disneys Frozen 2 received mixed reviews, but the box office results were enough reason for Disney to add Frozen 3 to their slate of upcoming movies. For Frozen 2, screenwriter Jennifer Lee once again co-directed with Chris Buck, using the sequel to open up the characters’ horizons to lands beyond Arendelle. This change in the narrative structure was somewhat surprising for a high-profile Disney sequel, but proved the studio wasn’t above taking risks despite pumping out so many “safe” sequels.
