Did you know that the first Harry Potter was released in 2001? Easy enough to look up, but amazing enough to realize that it has been 9 years since J.K. Rowling’s books were transformed into movie magic. To make it a perfect 10, Deathly Hollows was split into two parts, the second to be released in 2011.

In celebration of the wizard whose name will now live as famously as Merlin, here’s my favorite trivia from all the Harry Potters, sourced from Internet Movie Database.

2001 “Harry Potter: The Sorcerer’s Stone”

3. The IMDB favorite trivia: 3 months after its release on November 16 in February of 2002, it became the highest grossing film after Titanic.

2. USA is the only country to call the first movie, The Sorcerer’s Stone. Every other country calls it The Philosopher’s Stone. Scenes involving those words had to be filmed twice.

1. Liam Aiken (http://www.imdb.com/name/nm0014582/) was originally given the role of Harry Potter, which was revoked one day later because they realized he wasn’t British (an J.K. Rowling was very specific about wanting a British principal cast)

2002 “Harry Potter: The Chamber of Secrets”

If you thought “Potheads” were scary before…

3. The IMDB favorite trivia: Harry Potter fans went to watch Scooby-Doo (released 2002, think Buffy & Freddie Prince Jr.) motivated solely by the need to see the trailer for The Chamber of Secrets.

2. Harry a.k.a Radcliffe wasn’t always rolling in Gringotts. The initial offering for his salary in this movie was £125,000 (approximately US $181,500), later renegotiated by the actor’s union to around £2,000,000 (US $3,000,000)

1. Moaning Myrtle, actress age 37 is the oldest “student” in Hogwarts. She’s followed by Tom Riddle, actor age 25.

2004 “Harry Potter and the Prisoner of Azkaban”

3. Illusionist Paul Kieve served as a consultant, teaching magic to members of the cast including Radcliffe and Watson and to create physical magical effects. He is the first illusionist to have worked on any of the series of films.

2. “In order to acquaint himself with his three lead actors, director Alfonso Cuarón had each of them write an essay about their characters, from a first-person point of view. Emma Watson, in true Hermione fashion, went a little overboard and wrote a 16-page essay. Daniel Radcliffe wrote a simple one-page summary, and Rupert Grint never even turned his in.”

1. As a main player in this story and Harry Potter’s life, Sirius Black gets two trivia of his own: (i) the tattoos on his body are borrowed from Russian prison gangs, identifying Black as a man to be feared and respected (ii) Black’s wanted poster, translated, says “more or less human”

2005 “Harry Potter and The Goblet of Fire”

In 2005, Radcliffe was 16, Watson was 15, and Grint was 17. It was a time of youth, and well… acne.

3. The IMDB favorite trivia:  A digital “spot removing” technique, used for TV shows such as Desperate Housewives, was used to clear up the more severe teen skin problems (make-up looked shoddy, especially up close)

2. Over 3000 girls showed up in the cast auditions for Cho Chang. Katie Leung, who won the role, had in fact not intended to audition, dropping by thanks to her father’s information, before her shopping trip.

1. The tongue flick, the primary marker of Professor Moody secretly Barty Crouch Jr. was invented by the actor, on the spot.
