The debut of Star Trek: Voyager was a big deal for more than one reason. Primarily, the series brought back the "ship show" to the franchise after Star Trek: The Next Generation ended. It was also the flagship series of the new United Paramount Network. Yet, the biggest deal was Kate Mulgrew as the first female ship captain to lead a series. Interestingly, Kathryn Janeway's signature coffee addiction was not a creation of the writers but came from Mulgrew herself. This helps highlight for audiences how integral writers and actors are to creating the characters they love.
