The most controversial role of Professor Snape
Of the six actors announced, Paapa Essiedu attracted the most attention as he took on the role of Professor Snape – one of the most complex and iconic characters in the entire Harry Potter series:

-
Comparisons to Alan Rickman : Alan Rickman became iconic with his portrayal of Snape, making it difficult to find a replacement and prone to comparisons, putting a lot of pressure on the new actor.
-
Difficulty in portraying depth : Snape is a complex character, with inner conflict and many layers of emotions. Many fans were concerned that the new actor would not be able to convey the subtlety and depth that Rickman brought to the role.
-
Inappropriate Appearance : Although the new actor is talented, some fans believe that they do not have the right appearance or charisma to recreate the "legendary" Snape.
-
Different from the original : Some people worry that changing the actor might lose the soul of the character that fans have loved from before.
-
Difficulty in reinventing the character : While some hoped for a chance to develop Snape's character in a new way, not everyone was willing to accept this change.
The casting of a black actor for the role of Professor Snape, despite the character being white in the original book, may stem from a desire to increase diversity and inclusion in cinema. It is also a way for producers to refresh familiar characters, create a different view of them, and at the same time reflect the diversity of modern society. Some opinions say that this change may lose the character's identity.
How do fans react to the new cast?
The Harry Potter fan community had mixed reactions when the new cast was announced. Some loyal fans were concerned that the new version would have difficulty surpassing the attachment to the legendary cast of the original film. However, many were supportive, believing that this was an opportunity to retell the story with more depth and emotion in the context of the thriving streaming platform.

When will the new Harry Potter series officially air?
The Harry Potter TV series will begin filming in late 2025 and is expected to release its first season in 2026, with filming taking place at Leavesden Studios, where the previous eight films were produced. JK Rowling will oversee the production to ensure fidelity to the original. The filmmakers promise to bring modern, emotional visuals while still maintaining the "magical, humane" spirit typical of the wizarding world.
The new cast of Harry Potter is opening a new chapter for a cultural icon. Despite the controversy, there is no denying the series' appeal to both old and new generations. Let's wait and see if the new trio can write their own magic!
