The season was the first to be filmed in Los Angeles, after production was moved from Vancouver, British Columbia, Canada. This move was done largely at the behest of Duchovny, who wished to be closer to his wife, Téa Leoni. Series creator Chris Carter opposed the move, although series director Kim Manners and Anderson approved of it, although to a less-vocal degree than Duchovny. The first half of the season also saw Mimi Rogers and Chris Owens' characters—Diana Fowley and Jeffrey Spender, respectively—become recurring characters.
