SeaQuest DSV : Synopsis, Pictures, Photos, Trivia, Filming Locations

During the first season, in the background of some scenes were recreations of actual marine biology experiments.

Don Franklin, Jonathan Brandis and Ted Raimi are the only cast members to have stayed with the show for its whole run.

At first, the show was intended to be a realistic portrayal of the near future. When the show suffered low ratings, however, it was allowed to go in a more fantasy-oriented direction that included stories about aliens, lost civilizations, and even the Greek god Neptune.

During the third season, several episodes were shown out of order. As a consequence, the character of Lt. Brody dies in one episode and then reappears in a later one. Similarly during the first season the episode in which Admiral Noyce is appointed UEO Secretary General aired after two episodes were broadcast with him already in this position.

The wetsuits used by the crew of the Seaquest were manufactured by a scuba diving equipment company named Seaquest, though the show was not named after the company.

Peter DeLuise guest-starred in the first season episode "Whale Songs" before he joined the cast in the second season to play Dagwood.

Roy Scheider disliked the direction of the show in the second season, gearing it towards more heavy science-fiction elements and requested to be released from his contract. NBC partially obliged, requiring him to appear in only three third season episodes.

The image of Captain Bridger's wife, Carol, is played by Brenda King, who is Roy Scheider's real-life wife.

When guest star William Shatner appears on a viewscreen, the ID code at the bottom reads "JTK NCC1701". This stands for "James T. Kirk", Shatner's character on "Star Trek" (1966) and the registry number of the U.S.S. Enterprise, Kirk's ship.
