Gillian Anderson was really keen to return to the character of Dana Scully but was hesitant about signing on for a 20-episode run. When she learned that Fox was only going to do a limited series of just six episodes, she was overjoyed.
With an initial audience of 16.19 million, this was the most watched episode of The X-Files (1993) since the Season 8 episode, This Is Not Happening (2001). DVR and streaming figures bumped that up to 21.4 million.
David Duchovny spent a lot of the filming of the first episode in the season suffering from strep throat.
This marks the first time an episode of The X-Files (1993) was filmed in Vancouver since The End (1998).
