This becomes a critical plot point in the second Artemis Fowl-based novel The Arctic Incident.
The first novel is a story about Artemis Fowl discovering a fairy underworld and then kidnapping a fairy police officer in the hopes of obtaining a ransom from the kidnapping.
The new movie will mostly focus on the first book in Eoin Colfer’s series, but according to Kenneth Branagh, some elements from the second book and beyond will also be brought in, including the fact that Artemis’ father is missing.
How much of that story is kept in the big screen version remains to be seen, but you can take a look at the new movie via the first trailer, below.
