Sometimes, a network feels the need to rework an already-shot pilot. This is nothing new, really, as it happens often enough. That said, pretty much directly after set photos of The CW’s live-action “Powerpuff Girls” series “Powerpuff” made their way online, a redo of the pilot was ordered.
We don’t really know the official reason why. News of this decision was sort of buried deep in a The Hollywood Reporter piece. According to the outlet:

“In something of a surprise, The CW’s live-action Powerpuff Girls project didn’t receive a series order but will be reworked for a new pilot to be shot off cycle. The show’s cast and creators remain attached to the project.“
“Powerpuff” (which is apparently what The CW will be calling the show) previously announced Chloe Bennet, Dove Cameron, and Yana Perrault as Blossom, Bubbles, and Buttercup Utonium, respectively.
Bennet will portray Blossom Utonium. Though she was a spunky, conscientious, Little-Miss-Perfect child who holds several advanced degrees, Blossom’s repressed kiddie-superhero trauma has left her feeling anxious and reclusive, and she aims to become a leader again — this time on her own terms.
Cameron will play Bubbles Utonium. Bubbles’ sweet-girl disposition won America’s hearts as a child. She still sparkles as an adult, but her charming exterior belies an unexpected toughness and wit. She’s initially more interested in recapturing her fame than saving the world, but she just might surprise us and herself.
Perrault is Buttercup Utonium. Buttercup was the rebellious badass of The Powerpuff Girls in its heyday. More sensitive than her tough exterior suggests, Buttercup has spent her adulthood trying to shed her Powerpuff Girl identity and live an anonymous life.
Nicholas Podany will be playing Joseph “Jojo” Mondel Jr., aka Mojo Jojo.
We’ll let you know what we hear about how this reshoot goes.
