Behind the scenes
- In Harry Potter and the Deathly Hallows: Part 2, Minerva McGonagall uses this spell to fend off Severus Snape and the Carrows. However, in the novel, the duel between McGonagall and Snape is much different from what is shown on the film. Although, it should be noted at one point in their duel she did use fire, though it was the fire from burning torches along the walls, she did not conjure the flames from her wand. However, during their duel in the film the fire from Great Hall's torches diminish. It is possible she might be using the fire from the torches like she did in the novel, although the flames have disappeared from the torch and then reappeared at the tip of her wand rather than simply moving through the air. Whether this is the case is unknown. Also, it did not inflict any burns or noticeable injuries, as Amycus and Alecto Carrow were both hit by the deflected spells and were only knocked down and incapacitated.
- This spell looks remarkably similar to the Blasting Curses that Hermione Granger and Harry Potter used against Nagini in Harry Potter and the Deathly Hallows: Part 1 and Part 2. However, it is doubtful that they are the same spell, as Confringo is used to blast an object, causing fire to erupt from it as a result, while this spell is used to create and direct a source of fire.
- During the duel between Minerva McGonagall and Severus Snape in Harry Potter and the Deathly Hallows: Part 2, the fire from the Great Hall's torches diminishes. It could be that McGonagall used that fire for her spell as she does during the duel in the novel or it could be that the director wanted the torches diminished to created a darker and more tense atmosphere for the duel.
- It is possible that this spell is Incendio Duo or Incendio Tria, given that both spells are used to create a large amount of intense flames, and that both are commonly used in Duels.
