Hannah McMechan and Danya Jimenez, known for “KPop Demon Hunters,” are developing a new crime drama titled “A Really Bad Person” for FX. Deadline and The Hollywood Reporter both report that this is their first series-development work, and that they are writing the project for FX Productions and Legendary TV. The series is described as a co-production between Legendary Entertainment and FX Productions. Both outlets characterize the show as a crime drama with additional comedic elements, though details on tone and plot are not fully specified in the reports. At this stage, the announcements focus on the creators’ involvement and the production setup rather than casting or release timing. The project’s further development will continue as writers build out the series, with FX and Legendary handling production through their respective companies.
