In Harry Potter and the Deathly Hallows, Professor Minerva McGonagall casts Piertotum Locomotor during the Battle of Hogwarts, bringing the castle's statues and suits of armour to life to defend the school against Voldemort's forces. The moment, shown in the 2011 film Harry Potter and the Deathly Hallows Part 2, became one of the series' most stirring displays of Hogwarts fighting back. Potter fans have since reused the incantation in edits, reaction videos and soundboards, where its Latin rhythm and protective intent still signal a magical call to arms.
