Lindsay Wagner's first appearance in "The Six Million Dollar Man" was supposed to be her last role honoring her contract with Universal. However, public reaction to the role was so strong that she was offered her own series.
When the series changed networks from ABC to NBC for its third and final season, Richard Anderson and Martin E. Brooks became the first actors in history to play the same characters on two different TV series on two different networks as they continued to appear in The Six Million Dollar Man (1974) which remained on ABC.
Jaime's body is reconstructed with parts similar to Steve Austin's, albeit smaller. The actual cost of rebuilding her is not revealed but is said to be less than the $6 million that it cost to rebuild Austin.
Also when the series changed from ABC to NBC, Lee Majors no longer guest starred on The Bionic Woman because he was still under contract with ABC. Since he was the main character ABC would not allow the crossover, and vice versa with Lindsay Wagner.
Max, the bionic dog was actually played by several German Shepherds. For example in the episodes The Bionic Dog parts 1 and 2, they needed a dog that wasn't afraid of fire, one that would just lay and allow you to pet him or lay in front of food without being tempted to eat it. They also needed one to get on a treadmill.
