The British actor has been cast as Severus Snape, the potions professor at Hogwarts. Alan Rickman played Snape in all eight Harry Potter films. Essiedu earned several nominations for his role in the BBC’s I May Destroy You and costarred with Saoirse Ronan in The Outrun, which premiered at the 2024 Sundance Film Festival.

Charlie plays a small role in the first book, but it does set up his role in the fourth book. Therefore, it is expected that the HBO series will do the same. HBO, while announcing the cast of the Weasley siblings, put out this statement:

The upcoming show recently cast four of the Weasley children. On Tuesday, August 19, HBO revealed the four young actors who’ll be playing Ron Weasley’s (Alastair Stout) siblings: Tristan Harland as Fred, Gabriel Harland as George, Ruari Spooner as Percy, and Gracie Cochrane as Ginny Weasley.
