Fake Mixed Race: Kyra Zagorsky, who is white, plays Vasquez, the daughter of Kellog. Kellog is played by Stephen Lobo, who is of Goan and Iranian descent. (This is assuming she's not adopted, of course.)
Fake Nationality: Rachel Nichols is herself American, playing someone from Vancouver. Her accent becomes obvious when Kiera and Alec say "sorry" to each other in the same scene. Fittingly, Kiera masquerades as someone from Portland in 2012.
Production Posse: Plenty of the actors are familiar faces from other Vancouver-filmed franchises like the Stargate-verse and the reimagined Battlestar Galactica. Only a few of them, like Roger Cross, have been involved in American-based TV shows.
Screwed by the Network: It's hard not to conclude that Showcase's executives dearly wish that Continuum would just die and go away already — they have barely promoted it at all since the first season, and they waited for over five months of total silence from Season 3's conclusion in June 2014 all the way to December of that year to finally (and quietly) announce Continuum's renewal for a fourth and final season of only six episodes. Season 4, in turn, is only set to air starting in September 2015, and on top of that the show has been bumped from its Sunday time-slot to a new position at 9 PM on Friday nights.
What Could Have Been: As mentioned above, Continuum only ran for 4 seasons, however creator Simon Barry said outright there was enough story in mind for 7 to 10 seasons if the show had aired for that long. One can only wonder what would have happened in those 3 to 6 extra seasons ...
(Garza) in Continuum's future, Everyone Is Bi. This is not evident in the series however, where only Garza's explicitly bisexual.
