Rick Berman makes his TNG debut as a Writer in this episode.
	After Berman initially rejected the idea of bringing back Lore, Piller changed his mind allowing Brent Spiner to double up for the role again.
	Originally, Keye Luke was considered for the role of Soong.
	Brent Spiner had to shoot alternate days as Lore/Data and Soong.
	The "Soong" makeup took four hours to apply.
	In a nod to continuity, Lore wears the Pakled uniform seen in "Samaritan Snare", after he claims to have been rescued by the plodding race.
	Brent Spiner had two and a half days of shooting on his own for this episode.
	The computer fails to record Data's command lockout code correctly if you compare our screencap with the line Brent Spiner delivers on the episode.
