Oldie But Goodie

Moaning MyrtleThe actress who played Moaning Myrtle was 37 years old at the time “Harry Potter and the Chamber of Secrets” was filmed. She is the oldest actress to ever portray a Hogwarts student.

Potty Mouth

Potty mouthRon Weasley’s character originally swore a lot, but Rowling’s publisher wouldn’t let her use that sort of language because it would’ve been inappropriate for young readers.

J.K. – Just Kidding!

J.K. RowlingRowling’s publisher suggested she use initials rather than her real name, “Joanne Rowling,” in order to appeal to male readers. She chose J.K., borrowing the “K” from her grandmother’s name, Kathleen. However, neither “Kathleen” nor “K” is part of her legal name.

Spoiler Alert

SnapeOnly Alan Rickman, the actor who played Professor Snape, knew his character’s fate before the release of “Harry Potter and the Deathly Hallows” because Rowling told him.

Botanical Inspiration

Hogwart plantRowling said the inspiration for the name of Harry’s school in the books, “Hogwarts,” may have unconsciously come from the name of a plant she saw in the Kew Gardens in New York City.

An Interesting Audition

Rupert GrintRupert Grint dressed up like his female drama teacher and rapped about Ron Weasley for his audition tape. His rap began, “Hello, my name is Rupert Grint, I hope you don’t think I stink.”


VoldemortContrary to popular belief, the ‘t’ at the end of Voldemort is silent. The name comes from the French words meaning “flight of death.”

Second Year Itch

    OMG Harry Potter is so cute. I often have dreams about him and in my dreams he has a six pack!

  • Brad

    #6 is wrong. If you look close enough, it says M.G. Mcgonnagal. And 1971, obvisouly she is not that old.

  • Teo

    Really now, HP is a lot times better than Twilight! But siriusly (hope you see what I did here) we can’t compare them!
    HP ALL THE WAY! It changed my life!

  • Naiek

    Voldemort doesn’t mean flight of death, it means Death Thief, Stealer of Death, or any other variation.
    Also, fun fact, in Catalan, it apparently means “wants death” (courtesy of Google Translate).

    • Noelia

      I don’t know what it really means, but I can assure you that google translate is wrong in this one buddy, ’cause I’m from Barcelona (Spain), speak Catalan since I can remember, and Voldemort (Vol de mort) means “flight of death” in my mother tongue language :)
