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.

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.
