Anyone familiar with the film Harry Potter and the Order of the Phoenix likely remembers how Sirius Black appears to be struck by a spell from Bellatrix Lestrange — a green flash, a fall through a mysterious archway... It looked like a typical death curse. But attentive readers of the books know: it was far more complicated. And far more frightening.
What the film Harry Potter and the Order of the Phoenix showed
In the movie version, Bellatrix seemingly uses the infamous 'Avada Kedavra' curse — a green beam, instant death. Clear, familiar to the magical world. However, the book describes something entirely different: the spell cast by Bellatrix wasn’t deadly. Sirius falls — but not from a killing curse.
What happened in the book
In J.K. Rowling’s novel, Bellatrix sends a stream of red sparks at Sirius — not 'Avada Kedavra', just a powerful energy blast. It knocks him off balance, and Sirius stumbles, falling through the strange archway with the Veil in the Department of Mysteries. And this is where it gets truly disturbing.

The Veil — a one-way passage
This archway with its fluttering, translucent curtain is not just a set piece. The Veil is an ancient magical artifact that separates the world of the living from the world of the dead. Anyone who passes through it dies — with no return. Even experienced wizards felt an eerie pull toward the Veil, heard whispers behind it — as if the dead themselves were calling to them. When Sirius fell into the arch, he didn’t vanish in a spell. He crossed a threshold. Forever.
Why it’s even more terrifying
Sirius wasn’t killed by Bellatrix’s malice. Not by a clear, deadly strike. But by cold, indifferent magic from which there is no escape. His death was not vengeance, not combat, not a dramatic hero’s finale. It was silence. It was the Veil, swallowing the most alive, the most freedom-loving character in the entire saga.
And that’s exactly why this scene remains one of the most haunting and heartbreaking in the entire Harry Potter story.
