Gillian Anderson declared that Stella Gibson is her favourite among all of the characters she has performed, even more than Scully from The X-Files (1993).
All of the episode titles are borrowed from lines in John Milton's epic poem "Paradise Lost."
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.
