The Castle of Cagliostro
While not technically Studio Ghibli films, "The Great Adventure of Horus, Prince of the Sun" (1968), "Panda! Go Panda!" (1972), "The Castle of Cagliostro" (1979), "Jarinko Chie" (1981), "Gauche the Cellist" (1982), "Nausicaä of the Valley of the Wind" (1984), "The Red Turtle" (2016), "Mary and the Witch's Flower" (2017) and "Modest Heroes" (2018) are sometimes grouped together with the Studio Ghibli library (particularly with the "Ghibli ga Ippai" home video collection released by Walt Disney Studios Japan) due to their ties to the studio.
