Eureka is an American science fiction television series that premiered on Sci-Fi Channel (renamed Syfy in 2009) on July 18, 2006. The fifth and final season ended on July 16, 2012. The show is set in the fictional town of Eureka, Southern Oregon (although in the pilot episode Eureka was located in Washington – and the origin of a diamond in the episode "Best In Faux" was shown as Eureka, California). Most residents of Eureka are scientific geniuses who work for Global Dynamics – an advanced research facility responsible for the development of nearly all major technological breakthroughs since its inception. Each episode featured a mysterious accidental or intentional misuse of technology, which the town sheriff, Jack Carter, dealt with, with the help of the town scientists. Each season also featured a larger story arc that concerned a particular major event or item. The series was created by Andrew Cosby and Jaime Paglia and produced by Universal Media Studios. While initially lacking in critical acclaim, Eureka was a ratings success for the network, averaging 3.2 million viewers during the second half of season three. In 2007, Eureka was nominated for the Emmy Award for Outstanding Visual Effects for a Series, and won the Leo Award for Best Visual Effects in a Dramatic Series. In the United Kingdom and the Republic of Ireland, the show airs on Syfy and is known as A Town Called Eureka, although it is also shown under its original title on the BT Vision platform. Synopsis Deputy United States Marshal Jack Carter stumbles upon Eureka while transporting a fugitive prisoner (his own rebellious teenage daughter Zoe) back to her mother's home in Los Angeles. When a faulty experiment cripples the sheriff of Eureka, Carter finds himself quickly chosen to fill the vacancy. Despite not being a genius like most members of the town, Jack Carter demonstrates a remarkable ability to connect to others, keen and practical insights, and a dedication to preserving the safety of Eureka. Eureka takes place in a high tech fictional community of the same name, located in the U.S. state of Oregon and inhabited by brilliant scientists. Camouflaged by an electromagnetic shield, the town is operated by a corporation called Global Dynamics (GD), which is overseen by the United States Department of Defense. The town's existence and location are closely guarded secrets. Cast and characters Main characters Sheriff Jack Carter, portrayed by
