Albus Dumbledore attempted to use this spell to help Mrs Norris, the cat of the school's Caretaker, Argus Filch, after his pet became the first victim of Salazar Slytherin's Basilisk during the reopening of the fabled Chamber of Secrets during the 1992–1993 school year. It was ineffective, however.
Behind the scenes
- It is possible that there are subtle differences between the process of petrifying victims depending on the whether the victim of the curse in question was subjected to it by wand and incantation, or by the stare of magical creatures. It is also possible that the Basilisk, being the powerful beast it is, is particularly strong. If so, it might be that Dumbledore's counter-curse would have worked if the Petrification was caused by a curse from a wizard or witch, but not from creatures.
