20 Things You Never Knew About Star Trek: Insurrection
13. Despite Spiner's Reluctance, There Could Have Been Two Androids In The Film
Michael Piller toyed with the idea of bringing Lore back to the franchise. He had last been seen in Descent part 2, where he was shot by Data. Though disassembled, death was never truly certain for Data's brother, so a return could easily have been achieved.
Piller took inspiration from Star Trek II: The Wrath of Khan for this idea. Lore would have returned, hell-bent on seeking revenge against both Data, and the crew of the Enterprise-E. While the exact reasons that this didn't progress as a story are a little vague, Spiner's reluctance to return even to the role of Data may have played a part.
In a similar move to Berman's idea of having two Picards, two Soong-type Androids would appear in the following film. B-4 is said to be a prototype android, far less sophisticated than Data, and certainly less advanced than Lore himself. While fans were disappointed that the evil twin didn't return, at least Spiner got to pull double duty one more time.
