Behind the scenes
- In an early draft of the script for the film adaptation of Harry Potter and the Order of the Phoenix, Arthur Weasley uses this spell to try and repel Nagini, but misses. This cannot be considered canon, however, as in the novel, Nagini strikes Arthur almost immediately after he draws his wand, before any spells can be cast.
