- What Could Have Been: Harlan Ellison wrote a screenplay in The '70s (it's still in print!) which was much closer to Asimov's anthology. Unfortunately, the plot (which looked back on Susan Calvin's life in a manner deliberately similar to Citizen Kane) and the FX-heavy scenes (which included a lost city in the Amazon, several alien planets, and a duel in what would later be called cyberspace) didn't fit the producer's vision and/or budget, so it was shelved. Oddly enough, some DVDs of the 2004 film came bundled with a copy.
