In the tenth season it is revealed that Scully and Mulder are no longer a couple, as she chose to leave him. At the end of the Season, Scully gets a vision, that at the beginning of season eleven is revealed to have come from her son, William. Over the course of season eleven, Scully and Mulder search for William. Skinner learns from the Smoking Man, that the Smoking Man, who is Mulder's father, also artificially impregnated Scully, and thus is William's father as well. In the third episode of the eleventh season, "Plus One", Scully and Mulder are intimate again. In the season 11 finale, "My Struggle IV", she reveals to Mulder that she is pregnant with his child. Chris Carter named Scully after his favorite sportscaster, Vin Scully of the Los Angeles Dodgers. John Doggett was likewise named after Vin Scully's longtime broadcasting partner, Jerry Doggett. Scully's character was also inspired by Jodie Foster's portrayal of Clarice Starling in the film "The Silence of the Lambs". Scully was a known name in UFO lore. In 1950 the less than credible "Behind the Flying Saucers" was published, written by "Variety" columnist Frank Scully. The name Scully was also used in 1976 film "All the President's Men", an obvious inspiration for the show, in a list of names who work for the Committee for the Re-Election of the President. The casting for Scully caused a conflict between Carter and the Fox network. Carter had chosen 24-year-old Gillian Anderson, whom Carter felt was perfect for the role. Of her audition, Carter said, "she came in and read the part with a seriousness and intensity that I knew the Scully character had to have and I knew [...] she was the right person for the part". However, Fox executives had wanted a more glamorous "bombshell" for the part (in a 2008 interview Anderson stated that Pamela Anderson had actually been the network's first choice), hoping that this would lead to the series involving a romantic element. This led Carter to insist that he did not want the roles of Mulder and Scully to become romantically involved. Carter decided Scully would be the skeptic to play against established stereotypes; typically on television the quality was attributed to a male. Because Duchovny was much taller than Anderson, during scenes where Mulder and Scully stand or walk next to each other Anderson stood on "the Gilly-Board", an apple box named after her.
