Gustav Mahler's Symphony No. 1, 2nd movement is featured at several points; however, to some degree, the 1st movement of that same symphony is heard in nearly every Star Trek production. Alexander Courage borrowed the opening sequence of Mahler's Symphony No. 1, 1st movement and used it, with slight alterations, as the opening sequence for the Star Trek (1966) theme song. Mahler himself had actually borrowed the same sequence from Johannes Brahms who had, in turn, borrowed it from Ludwig van Beethoven.
The lead guest star is named Inspector Kashyk, after the Wookiee home planet in the "Star Wars" galaxy.
Along with Jeffrey Combs, J.G. Hertzler and Thomas Kopache, Randy Oglesby is one of only four actors to play seven different characters on "Star Trek". He played a scholar in Loud as a Whisper (1989), Ah-Kel, Ro-Kel and Silarin Prin in Star Trek: Deep Space Nine (1993), Kir in Star Trek: Voyager: Counterpoint, and Trena'L and Degra in Star Trek: Enterprise (2001).
When Janeway and Kashyk are in the mess hall, Pyotr Ilyich Tchaikovsky's Symphony Number Four, 2nd movement plays in the background.
