Trivia

Gillian Anderson declared that Stella Gibson is her favourite among all of the characters she has performed, even more than Scully from Los expedientes secretos X (1993).

All of the episode titles are borrowed from lines in John Milton's epic poem "Paradise Lost."

Jamie Dornan originally auditioned for the part of a police officer.

Many characters are named after guitars or things related to that world, like makers (ex. Spector, Burns, Stagg). Smith (named for Paul Reed Smith or PRS guitars). Benedetto (taken from a jazz guitar company). Stella Gibson is actually a double guitar name.

Jamie Dornan was born in the same city where the story develops (Belfast, Northern Ireland).
