Before the seventh season aired, Duchovny filed a lawsuit against 20th Century Fox, claiming that Fox had undersold the rights to its own affiliates, thereby costing him huge sums of money. Eventually, the lawsuit was settled, and Duchovny was awarded a settlement of about $20 million, but the lawsuit put strain on Duchovny's professional relationships. Neither Carter nor Duchovny was contracted to work on the series beyond the seventh season; however, Fox entered into negotiations near the end of that season in order to bring the two on board for an eighth season. After settling his contract dispute, Duchovny quit full-time participation in the show after the seventh season. This contributed to uncertainties over the likelihood of an eighth season. Carter and most fans felt the show was at its natural endpoint with Duchovny's departure, but it was decided that Mulder would be abducted at the end of the seventh season and would return in 12 episodes the following year. The producers then announced that a new character, John Doggett, would fill Mulder's role.
