In a new interview about X-Files comic books Frank Spotnitz brought up the demand for a Millennium movie:
“…Every single show we did with Chris at 1013 I have great affection for. Especially ‘Harsh Realm’ and ‘Lone Gunman’ I think ended before their time. And I have to tell you, everywhere I go people are always asking me if there’s going to be a ‘Millennium’ movie or something, so I suspect there’s a hardcore audience out there that’s still wanting it.”
