Lindsay Wagner's first appearance on L'homme qui valait 3 milliards (1974) was supposed to be her last role honoring her contract with Universal. However, public reaction to her was so strong that she was offered her own series.
When the series changed from ABC to NBC, Lee Majors no longer guest-starred on this show because he was still under contract to ABC, and since he was the main character, ABC would not allow the crossover, and vice versa with Lindsay Wagner.
Although two Wonder Woman TV movies had already aired by this time (one in March 1974 and another in November 1975), this was the first weekly TV series to feature a female superhero as the lead character, premiering three months before the Wonder Woman TV series.
The bionic jump action sequences, performed by Lindsay Wagner's stunt double Rita Egleston, was of her jumping backwards onto an inflated bag below, landing feet first. This was filmed in 60 frames per second and then reversed.
When the series changed networks from ABC to NBC for its final season, Richard Anderson and Martin E. Brooks became the first actors in history to play the same characters on two different television series on two different networks, as they continued to appear in L'homme qui valait 3 milliards (1974), which remained on ABC.
