With DC Comics off the table, WB IPs that could work in Epic long-term.
Lord of the Rings - The obvious, especially because it can enable a lush forest which is a missing aesthetic.
Looney Toons - The other obvious. It could enable a “zany,” kid-friendly land that complements Nintendo and Dragons but still have a very different vibe.
Scooby Doo - I’m still an advocate for a Scooby mini-land/attraction in Dark Universe. And, honestly, Scooby x the Monsters at FFN demonstrates the potential of it.
Dune - This would be a choice. It’s basically a space LotR. Sci-Fi has always been Universal’s lacking genre, and this would fill it while still allowing it to feel “fantasy” in that way Universal excels. I’m actually not a big fan of this personally, because its action is somewhat muted compared to something like…
Mad Max/Road Warrior - Now for something completely different and unexpected. It can support an elaborate stunt show (WaterWorld meets Lights Camera Action), a high speed thrill ride, and be aesthetically different from anything anywhere else. If there’s one major hurdle, it’s almost TOO adult—arguably more than Dark Universe.
Austin Powers - Maybe this should replace Fear Factor, but can you imagine a land centered on 1960s/1970s London?
