- The Cast Showoff: Brent Spiner gets to play six different personalities.
- Creator Backlash: Spiner actually doesn't think too highly of his performance in this episode. Since work on "Thine Own Self" had literally just wrapped the night before shooting this episode, he didn't feel he had the time he needed to fully explore all the characters that inhabit Data.
- Name's the Same: This episode shares its title with a licensed novel released four years earlier.
