Poseidon
Initially, Poseidon was created solely for the opening credits of the show, and nothing else. Turns out, the fans wanted him to appear in the show so badly that he ended up appearing in two episodes in the second season.
Female Directors
Considering the show is so focused on female empowerment, there were hardly any episodes directed by women. From the 100 plus episodes, only five were directed by women, two of which by Renée O’Connor. Eric Gruendemann discussed this topic with the Los Angeles Times, saying that there weren’t enough qualified candidates who knew about visual effects as well as action. “We feel bad about it,” he added, “but we’re not guilty because we’ve tried.”
