This was the first appearance of the Tellarites in the "Star Trek" franchise since Star Trek IV: The Voyage Home (1986) 17 years earlier.
The space station visited by the bounty hunter Skalaar and Archer was a reuse of the Cardassian repair facility CGI model from Star Trek: Deep Space Nine (1993).
A D'Kyr-type Vulcan ship can be seen docked at the space station with its warp ring in a horizontal position. This is the first and only time we see the ship in this type of configuration.
This episode was directed by Roxann Dawson, who played B'Elanna Torres in Star Trek: Voyager (1995).
