After his great-uncle's death, Francis Thurston finds his notes on a strange clay figure: an octopus-headed, winged monster carved by a young artist from his dreams. Thurston pieces together a police raid on a cult in the Louisiana swamps and the account of a Norwegian sailor whose crew landed on a city that had risen from the sea. There they woke Cthulhu, a vast creature sleeping beneath the Pacific, and only the sailor came back.

Free to use

  • The 1928 story: Thurston, Professor Angell, Inspector Legrasse, the sailor Johansen, the cult and the sunken city R'lyeh.
  • Cthulhu as Lovecraft describes him, and the chant "Ph'nglui mglw'nafh Cthulhu R'lyeh wgah'nagl fhtagn."
  • The structure of an investigation pieced together from documents.
  • Any version: a podcast-style horror film, a modern investigation, a series.

Watch out for

  • Lovecraft's later stories each have their own date: check that a story was first published before 1931 before you borrow from it.
  • Stories, characters and names that other writers added to the Mythos after Lovecraft are protected. So are role-playing games, their art and their trademarks.
  • New translations are protected. Use the original English or an old translation.
  • AI models have seen countless fan images of Cthulhu. Describe Lovecraft's creature in your art direction and check the result against the text.

  2. 2Attach it to a film project and ask for the characters, places and objects. Create the clay figure and Cthulhu as story elements.
  3. 3Write the art direction: a professor's study in Providence, a swamp at night, a city of impossible angles under a grey sky. Add a style image of your own.
  4. 4Ask for the scenes, then the shots; keep Cthulhu mostly unseen until the end.
  5. 5Generate the frames in Storyboard, then the clips in Production.

How a whole book becomes scenes and shots: novel to storyboard.

Questions

Is Cthulhu public domain?
The Call of Cthulhu was published in 1928, so it is free in the US, and H. P. Lovecraft died in 1937, so it is free in the EU and the UK. The creature as he wrote it is free; later games and stories by others are not.
Can I use other Lovecraft stories?
Most of what he published in his lifetime is old enough, but check each one's date of first publication before you use it.
Can I use designs from a Cthulhu game?
No. A game's art, rules and trademarks belong to its publisher. Design your creature from the story.
