"Alone Again, Natura-Diddily" was written by Ian Maxtone-Graham and directed by Jim Reardon as part of the eleventh season of the show (1999–2000). When the writing staff conceived the idea for the speedway parts, they were thinking that it would be a great opportunity for them to get several NASCAR drivers to make guest appearances in the episode. However, according to Scully, they could not get a single one because "they were all concerned about the way we were portraying NASCAR". Speedway racing is depicted in a negative light in the episode, with an overemphasis on crashes.
