A media institution is an established organization that creates and distributes media products. The document discusses several potential media institutions that could distribute a horror/thriller film, including major studios like Disney and specialized horror distributors like Twisted Pictures. Disney and other large companies sometimes distribute horror films through subsidiary brands to avoid stigma. Twisted Pictures and similar firms focused solely on horror would be ideal since they have experience and fans in the genre. In the end, any company with experience in horror distribution or strong global connections could effectively distribute the film.
