Nigel Bennett (LaCroix) wrote a series of vampire novels loosely inspired by his work on Forever Knight, called the "Ethical Vampires" series. There were also three tie-in Forever Knight novels published after the show's completion, written by other authors.
In an interview with Geraint Wyn Davies in the Season Two DVD Collection, Davies revealed that he, Catherine Disher, John Kapelos, Gary Farmer, Deborah Duchene and Nigel Bennett all tested reading the voice over given in the introduction of each episode before finally deciding to use Nigel Bennett's reading.
Originally "Forever Knight" was a two-hour made for TV movie pilot titled "Nick Knight (1989)" starring Rick Springfield as the title character.
