Jimmy Olsen was a photographer for the Daily Planet. He met Clark Kent when he started working for the paper in his early 30s, and continued to work there even through the time the Daily Planet was temporarily taken over by Warfield Publications. Jimmy also had a relationship with Lois Lane's sister Lucy and would visit her during her weekends away from the all-girls prep school that she attended. It was during one of those visits that he saw Supergirl in action, though he never revealed this news to the outside world when she departed after finding the Omegahedron.
- Jimmy Olsen was played by Marc McClure in the Donnerverse Superman movies from Superman: The Movie to Superman IV: The Quest For Peace and also in Supergirl.
