The Hollywood Reporter

"We couldn't quite figure out a model similar to Stargirl and couldn't quite get there," CW president Mark Pedowitz says in a wide-ranging interview with The Hollywood Reporter. "We were hoping to have it start at HBO Max and take a second run on The CW, but we couldn't figure out how to do it and couldn't make it all work." As for The 100 prequel series, he says: "The 100 prequel is still in discussions at the studio level. I'd like to see it happen. I'm comfortable with where the prequel spinoff episode we did this past season. It's not a pilot; the earliest that would happen would be probably summer 2022, if that happens. We may end up deciding that we can't put the pieces together and it won't happen."
