STEVEN UNIVERSE: THE MOVIE (2019) 6 p.m. on Cartoon Network. Rebecca Sugar became the first solo female show creator at Cartoon Network when she created “Steven Universe.” Since its 2013 debut, the show has won a Peabody Award, been nominated for five Emmy Awards and gained applause for being a standard-bearer in L.G.B.T.Q. representation in animation. The series gets the movie musical treatment here, with a story that involves Steven (voiced by Zach Callison) saving the world after the arrival of an alien threatens the continued existence of life on earth. Chance the Rapper, Gallant and Aimee Mann are among the musicians who collaborated on the movie’s original music; Patti LuPone and Christine Ebersole are among the vocal talent involved. “With the show, we like to take things that feel familiar and dig into them,” Sugar said in a recent interview with The New York Times. “So, I wanted to approach a ‘Steven Universe’ musical that way: These are things you recognize from other musicals, but with these characters.”
