Tannhauser Gate

The Tannhauser Gate is a location originally referred to in dialogue in the 1982 film Blade Runner, and again in the 1998 film Soldier.

Blade Runner
In the 1982 film Blade Runner, the replicant Roy Batty, played by Rutger Hauer, refers to it while recounting his experiences as a soldier. Given the fact that Earth has offworld colonies in Blade Runner, and the typical functions of devices incorporating the word "gate" in science fiction, fans of the film have suggested that the Tannhauser Gate is a stargate or similar construct providing faster-than-light travel between star systems, perhaps located near or in orbit of a colony named Tannhauser.

Soldier
In the 1998 film Soldier, the soldier character Todd (played by Kurt Russell), was a veteran of the Battle at the Tannhauser gate. The film's director Paul W. S. Anderson added this detail, however, so that it can only be read momentarily on a computer screen. The gate is also mentioned in dialogue.

References to the gate
Perhaps in a reference to Blade Runner, or through an independent resource, the Japanese animation series Gunbuster created by Gainax also makes several references to space travel through a Tannhauser Gate. In the computer game Homeworld, the player must save the Bentusi from Taiidan forces at a place called Tenhauser Gate.
