Jeff Goldblum was cast as Zeus after Hugh Grant, originally attached to the role, had to withdraw due to date availability issues.

Billie Piper joined the cast in a minor role as Cassandra.

Filming took place in Spain and Italy, with production starting in August 2022.

The gardens of Zeus and Hera's palace were filmed at the Villa d'Este in Tivoli, Italy.

Several outdoor scenes were shot at the large semicircular Plaza de España in Seville, Spain, along with other locations around Málaga, Almería, Madrid, and Cádiz.

The series was created by Charlie Covell as an eight-part one-hour show produced by Sisters Media for Netflix, with Georgi Banks Davies as lead director and Runyararo Mapfumo directing the second block of episodes.

Netflix cancelled Kaos in October 2024 after just one series, despite generally favorable reviews (74% on Rotten Tomatoes and a Metacritic score of 70).
