No, actually the decision was made after they were finished filming the season. They had to do reshoots because of it.
Indeed, and actually Prodigy hasn't quite been cancelled
yet. Season 2 is coming out (and continued production while it was "cancelled"), while a season 3 is still possible if the show does OK on Netflix.
In a recent Collider interview (
https://collider.com/star-trek-prodigy-dan-kevin-hageman/ ), the Hagemans talk about the fan reaction (mentioning specifically the selling out of toys, books and the famous banner). They felt devastated after getting the bad news.
Regarding the season 2 finale, they say: "
Season 1 kept getting bigger and the finale of Season 1 was huge, and then now we gotta go bigger. So now we're at the end of Season 2 and you’re on a little TV show budget, and we're just trying to make it as big and as amazing as possible."
Not sure how I feel about this, the ambition is nice but for me you don't have to "top" the ending with each new season. Lower stakes can be nice.
There was internal discussion about Drednok having a crazy voice/attitude, but the Hagemans decided that a soft and silent villain would actually be more scary. I applaud this choice.
They would love to see the Prodigy characters being used in other Star Trek material, including live action series, "Those Old Scientists" style.
One of the themes of season 2: "
There's so much that these kids can learn from their elders at Star Trek, but there's also an equal amount of stuff their elders can learn from the kids – the joy they have, the sense of adventures they have. Sometimes some of that is missed by Admiral Janeway."
Apparently, VA Janeway also learns from the Prodigies as well as the other way round.
