In February 2021, Mattel announced that Mattel Television was producing a Monster High live-action musical movie as well as a new animated series. The TV movie is set for release in 2022, and it will air on Nickelodeon in the United States. Jenny Jaffe (known for Big Hero 6: The Series) and the writing team of Greg Erb and Jason Oremland (known for Princess and the Frog and Playmobil: The Movie) are attached as the movie's writers.
This will be the second attempt at making a live-action musical based on the franchise. Back on June 3, 2010, The Wall Street Journal reported on the various ways that Mattel intended to promote Monster High, and one project was a live-action movie musical. It was said to be co-produced with Universal Pictures and directed by Ari Sandel. The report elaborated that the duo envisioned the product as "'Beetlejuice' meets 'Grease' meets 'The Addams Family' meets 'Edward Scissorhands'." It is unknown if any aspects from this concept will be carried over to the 2022 version.
