Bedknobs and Broomsticks was one of my favorite movies as a child. I recently wanted to write a Harry Potter crossover fanfic where Eglantine Price is instrumental in defeating Grindelwald and later teaches a young Minerva McGonagall the spell she later uses to animate the statues and armor to defend Hogwarts ("Substitutiary Locomotion" in Bedknobs and Broomsticks, "Piertotum Locomotor" in Deathly Hallows). Pretty nerdy, I know.
