I'm confused. In the OOTP film, Sirius gets hit by the killing curse, yet he looks at Harry for at least 3 seconds before dying. I thought Avada Kedavra instantly kills someone on contact? 90.199.56.44 22:41, 24 May 2009 (UTC)

And you are right. It was a filmmaker's error. -- Seth Cooper ^{(Owl Post)} 23:17, 24 May 2009 (UTC)

In the books, Avada Kedavra causes instant death, and it isn't revealed which spell Bellatrix used to knock Sirius through the Veil. The dying gaze was added by the filmmakers, probably to enhance the emotional impact of the scene, a bit like DH32. ★ Starstuff ^{(Owl me!)} 23:20, 24 May 2009 (UTC)
