Ghost Master (2019)

Akira Kurosawa is a nerdy movie buff who works on low budget romantic comedies while dreaming of becoming a horror master. After being abused by his mentor, “the master” he finally decides he’s had enough and opens a door allowing an evil spirit to wreak revenge on those who have been cruel to him. But much like the movies he loves, once a spirit is unleashed – it can’t be controlled and starts to kill everyone!
