This may come as a shock, but it’s already been more than 18 years since the first Harry Potter movie hit theaters. That’s right, the first flick came out in November 2001, but it seriously feels like just yesterday that viewers were watching Harry Potter, Ron Weasley and Hermione Granger practice their magic at Hogwarts, doesn’t it?

It’s safe to say that no matter how much time passes, the movies, which were based off of J.K. Rowling‘s epic seven-part book series, will forever hold a place in fans’ hearts. For those who forgot, they were all about a young wizard named Harry, who along with the help of his friends, had to take down the most powerful and evil wizard of all time — Voldemort.
