The series' original cancellation in 2000 was due to a dispute between Wilson and the producers of the show over Wilson being offered the role of Jean Grey in X-Men (2000) and asking to be released from her contract early so she could participate. The producers refused and Wilson refused to renew her contract. It would appear, this had Peta Wilson blacklisted for the rest of her "Hollywood" career.

According to creator Joel Surnow, nobody liked Roy Dupuis ("Michael") the first two episodes because of the slow way he interpreted his role and his lack of emotions, but by episode 3, people understood he'd made the right choices for his part.
Peta Wilson was the second or third actress who read for Nikita. She was selected after they had auditioned some 200-300 actresses, according to Joel Surnow.
The show ran five seasons. The season number determined the number of words in an episodes title (i.e., all third season episodes had three words in their title).
