It's been one whole decade since Harry Potter stepped up the battle against dark wizard Voldemort in The Deathly Hallows: Part I. Such was the vast scale of J.K. Rowling's final Potter book (clocking in at 607 pages) that the story had to be chopped in half and presented in two big screen instalments.
The penultimate movie in the blockbuster franchise left its family-friendly roots far behind in this darkly engrossing entry, which for the main throws Harry (Daniel Radcliffe), Hermione (Emma Watson) and Ron (Rupert Grint) into the wilderness. There, they must survive on their wits alone and attempt to avert the coming apocalypse, all the while as Voldemort's (Ralph Fiennes) Death Eaters have infiltrated the Ministry of Magic.
This was the first act in a staggering climactic two-parter that closed one of the biggest film franchises of all time. But unlike the action-packed Deathly Hallows: Part II, this is a more contemplative affair that adds depth to the increasingly complex Harry/Hermione/Ron triangle.
To celebrate the film's 10th anniversary, here are 10 fun facts you may not know about the movie. Of course, someone could have used an obliviate spell on you. Whatever – scroll down to check out our list.
