Legally Black is a group of young social justice advocates whose aim is to combat the way black people are portrayed in media. They went viral for a campaign they did where they took well-known movie and television posters and replaced the white characters with themselves, including Harry Potter, Skins and Doctor Who. When Channel 4 reached out to the group to work on a project for Black History Month, they were more than happy to collaborate and recreate well-known Channel 4 shows.
