Kate Mulgrew doesn't know if a live-action Janeway can be recaptured
Star Trek: Voyager fans have been calling for a live-action Admiral Janeway show since Star Trek: Prodigy began, if not before. Voyager ran for seven successful seasons, and Prodigy, where Kate Mulgrew lends her voice to Admiral Janeway, just finished up its second season. And the cry for more of Janeway continues. Why? Because Captain Janeway is/was one of the best captains in Starfleet, and Kate Mulgrew herself is simply an amazing human being.
So when she was asked about returning to live action at the San Diego Comic-Con, she said that "once you do it, and I did it for seven years, I don't know if it can be recaptured." So a return for her would have to be "novel," "authentic," and "impeccably done."
In the clip posted to Tiktok by @onlythejaneway, Mulgrew mentions Patrick Stewart's show, Star Trek: Picard. She didn't specify as to why it was mentioned, although she did add he was a splendid captain with a beautiful voice. Perhaps it was to point out that the captains can return successfully.
It's wise for Mulgrew not to want to jump into a live-action Janeway series without a clear idea of what she wants. We watched Captain Janeway for seven years and now for two as an admiral, and she embodied a character that cannot be recreated by anyone else. But Janeway is also a character that has to have purpose, a need to return. So just a revamping or a rebooting of Voyager would not work. There would need to be a solid reason that Janeway is coming back, and I don't think that would be just to fly another mission. It would have to be high stakes and high concept, almost cinematic. That's what it would take to bring Mulgrew back to either a streaming channel or a movie screen. And we'd accept either one gladly.
