Mad Heidi is an upcoming English-language Swiss/Finnish film directed by Johannes Hartmann and produced by Valentin Greutert. The film stars Alice Lucy in the title role, and Casper Van Dien as the villain President Meili, as well as David Schofield (actor) as Heidi's grandfather Alpöhi.  Dubbed as the "World's First Swissploitation Movie", it is a parody of the Swiss children's storybook character Heidi, set in a dystopian Switzerland. 
The production team spent three days shooting the first promo teaser in August 2017. The teaser starred Jessy Moravec in the title role.  In an elaborate casting process, the role has been recast in 2021.
