Babylon 5: Thirdspace (1998)


Babylon 5: Thirdspace is a 1998 American made-for-television film that is part of the Babylon 5 science fiction universe. It was written by J. Michael Straczynski and directed by Jesús Salvador Treviño.

The movie was originally shown on 19 July 1998 on the TNT cable network, during the run of season five (originally being shown between “Movements of Fire and Shadow” and “The Fall of Centauri Prime“). In addition to members of the regular cast of the Babylon 5 TV series, it features the notable guest-stars Shari Belafonte (playing Dr. Elizabeth Trent) and William Sanderson (reprising the role of “Deuce” that he played in the episode “Grail“).

The horror-based story, which ties into the Shadow/Vorlon plotline, centres on the return of an ancient and overwhelming alien force which had once attempted to destroy life in the Milky Way.

Also known as Babylon 5: Guardians (working title, US).


An enormous artefact is discovered in hyperspace and is towed to Babylon 5 for investigation. The xenoarchaeology corporation Interplanetary Expeditions sends a representative, Dr. Elizabeth Trent, to take control of the artefact’s examination.

The artefact begins to influence the dreams of many inhabitants of Babylon 5, eventually controlling many of them during their waking hours as well. These thralls, led by Deuce, first demand that the excavation be accelerated, and then become increasingly violent towards the rest of the Babylon 5 population. Dr. Trent conjectures that the artefact is a Jumpgate that takes one neither to normal space nor to hyperspace but to a “third” space (hence the movie’s title). With the reluctant support of her colleague, they order the device to be turned on, without notifying Captain Sheridan.

Sheridan and Delenn visit Lyta Alexander, who, transmitting a “race memory”, explains that the gate was built by the Vorlons a million years ago with a purpose that cannot be expressed in human terms except as an attempt to make contact with the gods. The Vorlons discovered that Thirdspace is a parallel universe inhabited by a violent, telepathic alien species even older and more powerful than the Vorlons that is bent on exterminating all life other than their own.

Long ago, the Thirdspace aliens telepathically converted a small army of Vorlons to fight and die for them. The ensuing battle ended in a stalemate; the non-thrall Vorlons shut down the gate, but the remaining Vorlon thralls prevented the artefact’s destruction by sending it into hyperspace where it was lost but preserved (in hopes that it might one day be reawakened). Lyta then telepathically informs Captain Sheridan how to deactivate the gate.

When the device is finally reactivated, the Thirdspace aliens stream out from the portal in small fighters and begin a devastating assault on Babylon 5, obliterating large cruisers with little effort. The Thirdspace fleet is highly advanced and the single-occupant fighters possess deflector shield technology, making them extremely hard to destroy. The violent behaviour of the individuals under the artefact’s control is intended to disrupt the station’s defences. The struggle is ended when Sheridan uses a thermonuclear device to destroy the artefact just as the first wave of Thirdspace heavy warships begins to emerge. Once the artefact is destroyed, the telepathic influence stops and the station returns to normal. Trent, shaken by the way in which the artefact affected her, turns over her final report and goes on an indefinite hiatus.

Sheridan and the others conceal the true nature of the artefact from those who ask questions and confidently assure themselves that the incident is unlikely to occur again. In private, Lyta broods with the knowledge that the artefact was only one of many mistakes the Vorlons have made.

Story Arc Significance And Continuity

Essentially a stand-alone episode, the film is set after the Shadow War (episode 406 “Into the Fire”) and before war was declared with Earth (episode 414 “Moments of Transition”). The presence of both Dr. Franklin and Delenn, along with changes to Zack Allan’s uniform, further place the events during or just before episode 409 “Atonement”, to the extent that its continuity problems can actually be resolved.

While a stand-alone story, it does include a scene in which Zack Allan finally reveals his feelings outright to Lyta Alexander, unaware that she is being telepathically dominated and not hearing a word he says. This sheds some new light on their somewhat uncomfortable friendship and his jealousy of her relationship with another telepath, Byron, that would occur in Season 5.

In the season 5 episode “The Fall of Centauri Prime”, Delenn (while talking to Lennier about themselves drifting in hyperspace) appears to refer obliquely to the events of this film by pondering, “Who knows what’s out there; maybe we’ll find a million-year-old jumpgate left over by the First Ones.”

The fictional artefact was designed by science fiction and fantasy artist Wayne Barlowe after the script was written. In the novelisation, the description of the artefact does not match what appears in the film. Most notably, the artefact in the novel formed into a jump gate that was larger than the station when it became operational. In the film, however, it rearranged itself and actually decreased in size.


  • When they finished editing the movie for broadcast, the producers found out that they were actually a few minutes short so the elevator scene with Zack and Lyta was added.
  • Thirdspace was the first of the TNT movies filmed, but the second one aired, in July 1998.
    • As it was actually filmed in late 1997, Claudia Christian was still part of the Babylon 5 cast at the time.
    • When it was finally aired, Claudia had been replaced in the recurring cast by Tracy Scoggins in the part of Babylon 5 Commander under Sheridan.
  • The artefact was designed in cooperation with Wayne Douglas Barlow, author of Barlow’s Guide to Extra-terrestrials.
