When B'Elanna Torres tries to comfort Tom Paris by bringing more TV shows, she says she has another episode of The Untouchables (1959). "The Untouchables" was produced by Desilu Productions which also produced Star Trek (1966).
The Space Commander remote that B'Elanna gives Tom is the original TV remote and is the origin of the term 'clicker.' Pressing the remote button caused a hammer to strike a tuned rod creating a distinctive clicking sound.
David Keith Anderson (Ensign Ashmore) worked on the Star Trek films and spin-off television series for fourteen years. He was the stand-in and photo double for the regulars LeVar Burton, Tim Russ, and Anthony Montgomery and played several characters on screen, most prominently the recurring parts of Armstrong and Ashmore.
The episode of The Untouchables (1959) that Tom is watching is Ma Barker and Her Boys (1959). One of the episode's guest stars was Louise Fletcher, who played the recurring role of Kai Winn in Star Trek: Deep Space Nine (1993).
The rifle props used in the nightmare sequences of the episode are carry over props from The Magnificent Ferengi (1998) used as Ferengi weapons.
