Behind the scenes
- "I'll make short work of this. Bombarda Maxima."
- —Umbridge uses Bombarda Maxima to break into the Room of Requirement.[src]
- In the film adaptation of Harry Potter and the Order of the Phoenix, Dolores Umbridge uses this to to smash through the entire wall that conceals the Room of Requirement in order to ambush Dumbledore's Army. The spell was only used in the film because in the book, Dobby arrives before Umbridge does, warning them, and the DA is caught by the Inquisitorial Squad while running away.
