While working in Roswell, New Mexico in 1947, young cop Arthur Dales (the brother of the Arthur Dales who started the X-Files) stumbles across a “negro” baseball player who is actually an alien with a love of the game hiding among humans. Darren McGavin - who played the first Arthur Dales in two previous episodes, filmed two scenes before illness forced him to step down from the project. M. Emmet Walsh was called in, and the script rewritten, to accept the changes. McGavin’s scenes are included on the DVD. The name of the team Josh Exley plays for is the "Grays," which is possibly based on the real-life Negro League baseball team the "Homestead Grays." This could also be a reference to the supposed race of aliens known as the Greys, that is often the basis for many films and television shows, including the X-files. The title of the episode is an offhand reference to the title of Bernard Malamud's baseball novel The Natural --- later adapted and remade in 1984 as a well-known film starring Robert Redford. Instead of "The Truth Is Out There", the text that appears at the end of the opening credits is "In The Big Inning". Guest starring: Jesse L. Martin as Josh Exley, M. Emmet Walsh as Arthur Dales

While Mulder is away in England, Scully is led by coincidences, chance, fate and possibly a higher power to a married man whom she had an affair with during medical school, and a look at the life she didn’t choose, forcing her to make choices about her future. This episode was written and directed by Gillian Anderson who plays Scully. This episode is the second of only two featuring non-diegetic music not composed by Mark Snow in the entire series. The song is The Sky Is Broken by Moby, although at one point it is diegetic when Mulder plays it on a boombox. In the opening of this episode, while Mulder lies on a bed, Scully is shown putting clothes on and leaving the room, possibly after having sex with him. The backstory regarding Scully, Dr. Waterson, and why his daughter hates Scully was originally much more involved and complicated, culminating with the suicide of Waterson’s wife after Scully had left medical school. The intended story, which had to be cut for time, is detailed in the commentary track by Gillian Anderson on the season 7 DVD extras. Trivia Fact: At 24:08 into the episode, as Dr. Waterson flatlines and Scully is attempting to get his heart going, the camera begins to pan back. The room is presumably empty as Scully yells for a nurse. If you are watching the widescreen presentation of the episode, a hand can be seen (presumably of the cameraman) being quickly withdrawn from on top of the I.V. drip monitor at the bottom right corner of the screen.

An entrepreneurial Hollywood producer, and college friend of Skinner, picks up the idea for a film based on the X-Files, however the agents find that the level of realism in their fictional portrayal is somewhat questionable. The theater audience in this episode largely consisted of crew members and their families as a 'thank you' for their involvement with the show. Originally the entire audience was to have been made up of this group, but Gillian Anderson became ill after the filming of "All Things", and production was pushed back a week. Extras were hired to fill the spots of people unable to adjust to the changed schedule.
