Steven Universe: The Movie is a 2019 American animated musical television film based on the animated television series Steven Universe created by Rebecca Sugar. The film is directed, co-written, produced and executive produced by Sugar and fellow longtime crew members Kat Morris and Joe Johnston, and stars Zach Callison, Estelle, Michaela Dietz, Deedee Magno Hall, and Sarah Stiles, alongside an ensemble cast reprising their roles from the television series. Steven Universe: The Movie takes place two years after the events of the series finale "Change Your Mind", and follows the Crystal Gems as they attempt to save all organic life on Earth from a deranged Gem with a history with Steven's mother.

The film was announced at San Diego Comic-Con 2018, and a short teaser trailer was later released on Cartoon Network's YouTube channel. At San Diego Comic-Con 2019, a trailer for the film was released, along with the announcement of a documentary based on the film's creation to be released along with the DVD. The film premiered on Cartoon Network on September 2, 2019, to critical acclaim.

The film takes place between the original Steven Universe series and its follow-up, Steven Universe Future.

After an introduction from the Diamonds ("The Tale of Steven"), Steven Universe, now 16 years old, greets the citizens of the Gem Empire. The Diamonds want him to stay to fulfill his mother Pink Diamond's role as a leader ("Let Us Adore You"), but he refuses. Back on Earth, the Crystal Gems celebrate their newfound peace ("Happily Ever After"). Almost immediately, a giant drill lands on the hillside, and Spinel, a deranged and cartoonish Gem, appears, announcing her intent to kill Steven and the rest of the Earth ("Other Friends"). Using a scythe-like weapon, she "poofs" Pearl, Garnet, and Amethyst back into their gem forms; her attacks also weaken Steven's Gem powers, though his body is unharmed. Steven manages to poof Spinel with the scythe.

Spinel has not been a contender in any CBUB matches.
