Congratulations, you barely earned this news. You found a link that didn't require checking a press release twice, and now you get to hear that Matt Dinniman signed with WME, which is the kind of thing that happens when a book series sells over 400,000 copies and holds the No. 1 spot in the top 100 paid audiobooks for TV on Amazon. This is an unofficial fan site, so we can say what we want: the man finally got a real agent, and it only took a bestseller and a competitive situation to do it.
The practical meaning for you, the reader who has been screaming about this series for years, is that WME will now work to develop Dungeon Crawler Carl for something, presumably a screen, which makes the recent casting announcement for Jeff Hays to voice Princess Donut in the show feel less like fan service and more like a negotiating point. You can read about that in Jeff Hays to Voice Princess Donut in Show After Fan Demand and then wonder if the audiobook narrator who made the character real will actually get to do it when the suits are done. Meanwhile, the series has already been reviewed in our own Book Six Review: The Eye of the Bedlam Bride Barely Worth Your Time, which tells you everything you need to know about how we feel about the franchise's current trajectory. A competitive signing at WME does not fix a weak book, and if you think a Hollywood deal will make book six read better, you are the kind of person who thinks a new cover fixes a bad story.
The single takeaway here is that Dinniman now has a major agency pushing a property that has already proven it can move units and hold a chart position. The open question is whether WME will treat Dungeon Crawler Carl as the chaotic, cat-driven, foot-throwing death game it is or try to sand it down into something that fits a streaming slot. Watch for the first development announcement. If it mentions "broad appeal" or "family-friendly," start worrying. If it mentions Princess Donut, Mongo, and a dungeon that wants to kill everyone, you might be fine. Until then, this is a piece of paper that says a book deal barely happened. Do not celebrate until you see a trailer.
