So, it's kinda funny that something similar just happened to me with my other much-loved childhood mystery series - The Three Investigators. I knew the 3Is were popular in Germany, but what I didn't know is that there have been 100 additional German books published in the series, and several of them have been translated into English to help German students learn the language. So suddenly, I'm confronted with an entire list of new-to-me 3I books! Wow. (Of course, I'll have to get over the fact that Jupiter Jones has been turned into Justus Jonas. Why? I have no idea! And Pete Crenshaw is Peter Shaw. Again, huh?)
Those wacky Germans. They made (through the International Disney branch) a couple of 3I movies. They were filmed in South Africa, which was fine for the one where they changed the story to relocate from a Greek Island to South Africa, but was awfully funny when it was supposed to be set in California and looked nothing like California. The movies are... cute, I suppose. The actor who played Jupiter was good; he had that sense about him that he was much older - maturity wise, not so much physically - than his actual age, like the Jupe of the books. But canon? Uh, let's just say these movies have less in common with the book canon than ASKOF has with the TB books. Yeah. They really are that far off. I guess we could consider this a "careful what you wish for" warning if we were hoping for any Trixie movies to somehow happen. That's certainly lottery-level long shots, though, since the books are out-of-print here, and no other country as inexplicably embraced them and kept the series going.
Meanwhile, there's another Nancy Drew show in the works. Meh.
