Jennifer Gatti (Libby) also appeared in Birthright, Part I (1993)/Birthright, Part II (1993) as Ba'el.
Some of the exterior shots used in this episode are reused shots from various Star Trek movies. The scene of Ensign Kim's return to San Francisco is a re-use of the air tram flight Admiral Kirk takes to Starfleet Command in Star Trek: The Motion Picture (1979). The exterior shot of Starfleet Headquarters is a re-use from Star Trek III: The Search for Spock (1984) and Star Trek IV: The Voyage Home (1986). Also an exterior night shot of the Golden Gate Bridge is a re-use from Star Trek II: The Wrath of Khan (1982).
There is a brief glimpse of a banner advertising the Old Town Festival in the Mission District of San Francisco as occurring on August 14th. This is one of the few instances of a month (rather than a stardate) being mentioned in a 24th-century episode.
When Kim comes up out of the subway, there are three colored shapes on the railing: a circle, triangle, and square. These were the original logo shapes for UPN and Star Trek: Voyager was one of the first flagship shows of that network.
There is a model of the Enterprise-D in Harry's quarters that can be seen after his meeting at Starfleet Command.
