* Jess was written out of the series due to Leanne Wilson wanting to return home to England.
* 'Fever Of The Hunt' was supposed to air much earlier, around the time of 'The Miracle', but it was held back for Sweeps Week.
* ActingForTwo: Adrian Paul as Cole and the underwear model whose form he copied in the episode where the latter is used to frame the former.
* ActorAllusion: Cole wields a katana to escape an underground museum vault, an obvious nod to Adrian Paul's ''Highlander'' series.
* IKnewIt: Mel being part Cirronian was called by several fans a while before it was officially revealed.
* NamesTheSame: Cole occasionally used the fake last name 'Hauser' after Mel spotted a reserved parking sign while Vic was asking for Cole's last name and decided to use it. Cole Hauser is also an American actor.
* WhatCouldHaveBeen: The show 'bible' originally had Mel as having a younger sister living with her. This character was dropped and replaced by Jess.
** This received a nod in one episode, where Mel claims to be Jess's older sister in order to have Jess be covered by Mel's medical insurance.
* WhatTheHellCastingAgency: Chyna as Rhee. Many fans didn't like it, and many potential fans were turned off by it.
* The series was never released on DVD in full. Lion's Gate did release a 'movie' of about three episodes compiled and edited together that they called ''Alien Tracker''. This was thought by many to be a move to see how well [=DVDs=] would sell. But, the fans saw it as a piece of junk and refused to spend money on it, possibly causing the studio to think full season [=DVDs=] wouldn't sell.
* [=SciFi=] Channel briefly aired the series, but only made it through a few episodes before pulling it.
* The fans did make an attempt to save the series, but failed to even reach the 5000 name goal in the petition. And the effort was beset by sabotagers, who used the names of legitimate signers to sign again with negative, trollish comments.
