Nobody is talking about THIS…

There’s a lot of discussion right now about the Harry Potter TV show casting a black actor as Snape. And believe it or not, I’m not here to pile on the decision. There are plenty of creators giving you their opinions on that. What I want to do is talk about something that almost nobody discusses — the self-imposed structural rules that govern these productions and make decisions like this almost inevitable.
If you want to understand why this keeps happening, you need to understand the BFI — the British Film Institute. They define themselves as a cultural charity and the UK’s lead organization for film and the moving image. The BFI has diversity standards, and those standards are tied to things that matter enormously to the people making these productions — awards eligibility, tax relief, and public funding.
BAFTA adopted the BFI diversity standards for film in 2019 and expanded them to television by 2022. To be eligible for British categories, a production must meet at least two of four standards: on-screen representation through diversity in cast and storylines, creative leadership and crew diversity, industry access through training and mentoring for underrepresented groups, and audience development strategies for underserved groups. Underrepresented groups are defined by the UK Equality Act of 2010 and include race, ethnicity, gender, gender identity, disability, sexual orientation, religion, age, socioeconomic background, and regional participation. If you don’t check those boxes, you’re not eligible for the awards.
But it goes deeper. The UK offers a 25 percent tax credit on qualifying UK productions. To access that credit, you must pass a cultural test administered by the BFI. Almost every film and TV show shot in the UK takes advantage of this — why wouldn’t you? The BFI administers both the cultural test for tax relief and the diversity standards, and those standards are a contractual requirement for all BFI public funding.
This is a British IP, shot in the UK, with a British showrunner and a largely British cast. Harry Potter will almost certainly be eligible for BAFTA consideration and will almost certainly be accessing UK tax relief. That means the BFI diversity standards apply. When your funding, your tax credits, and your awards eligibility are all tied to checking these boxes, the casting decisions start to make a lot more sense. It goes well beyond a casting director’s personal preference. They’ve tied their own hands with self-imposed rules, and it’s not discussed nearly enough because it’s easier to react to the surface-level decision than to understand the system that produced it.
