Eureka is a film directed by Nicolas Roeg, released in 1984, starring Gene Hackman, Rutger Hauer, Mickey Rourke, and Joe Pesci. The film is about the story of a Klondike prospector, Jack McCann (Hackman) who strikes it rich, only to fear that his daughter Tracy (played by Roeg's then wife, Theresa Russell) and son-in-law (Hauer) are scheming not only for his wealth but his very soul. Greedy investors (Pesci, Rourke) are also swooping down for Hackman's fortune.

The story is loosely based on the real-life murder of Sir Harry Oakes in the Bahamas in 1943.

Eureka is an American science fiction television series set in a town inhabited entirely by geniuses. In the UK, it is known as A Town Called Eureka.

The Sci-Fi Channel has renewed Eureka for a third season of 13 episodes. To what extent this will be affected by the 2007-2008 Writers Guild of America strike is unknown, although co-creator and Executive Producer Jaime Paglia has stated that it could in fact result in a larger order than the original 13 as a way to "help offset the financial impact of the production push."

Eureka! was a Canadian educational television series which was produced and broadcast by TVOntario in 1980. The series was narrated by Billy Van, and featured a series of animated vignettes which taught physics lessons to children.

Eureka! was also broadcast on some PBS stations in the United States.

Arctic prospector Jack McCann, after fifteen years of solitary searching, becomes one of the world's wealthiest men when he literally falls into a mountain of gold in 1925. Years later, in 1945, he lives in luxury on a Caribbean island that he owns. But his wealth brings him no peace of mind as he copes with Helen, his bored, alcoholic wife; Tracy, his dear, but headstrong, daughter who has married a dissolute, philandering social-climber; and Miami mobsters who want his island to build a casino. His life is entangled with the obsessions of those around him with greed, power, and debauchery against a background of occult symbolism. Written by Jerry Caplin

Was originally conceived as an animated series.

The first season episodes were not aired in the order intended by the show's creators. This is suggested by the episodes' production numbers which are displayed on the Sci-Fi channel's Eureka website next to episode titles quite often. There are some small inconsistencies when watched closely, but such inconsistencies are minimal and were intentionally controlled. In podcast commentaries with the show's creators and star Colin Ferguson, they confirm that the production order is in fact the order they intended the show to air, but the network executives changed the order to try and place stronger episodes earlier in the run as to help attract viewers. As such, the creators were able to make minor changes in editing and sometimes ADR dialogue in later episodes (such as removing the explicit mention of Zoe's first day at school) to try to eliminate audience confusion.
