So, this isn't Precure related, but it is related to Toei and the magical girl genre, so I figure a few people here might find this interesting...
So back in 1990, well before Precure or Ojamajo Doremi, Toei had a live action show named Bishoujo Kamen Poitrine, in which a young girl transformed into a magician themed hero to fight evil. The show was developed by none other than Shoutaro Ishinomori, the creator of Kamen Rider and various other Tokusatsu series.
Commercial for Poitrine toys.
So why am I bringing this series up now? Well it's been revealed that Poitrine is going to make a comeback in the new Kamen Rider movie coming out at Christmas. She appears to help out Kamen Rider Wizard in his segment of the movie, as seen here:

It's pretty cool to see this forgotten character return to the screen, especially since this gives us the first ever crossover of a Kamen Rider with a magical girl. It might not be Precure or Sailor Moon, like many of us envisioned, but I look forward to seeing how these two work together in the movie.
