EXCLUSIVE DETAILS REGARDING OBI-WAN KENOBI AND ANDOR by Matt Hudson
One piece of news I didn’t expect, but which line up with what leaks we’ve seen so far, is that “The Volume plays no part in Andor”. We’ve seen actual sets being built and honestly this sounds like a welcome change from Mando and TBOBF which are both filmed in the Volume (and sometimes I can tell).
The article also says it will be “gritty, dark, and aimed at a more mature audience than previous shows.” I suppose we could always expect it to be dark and gritty based on the tone of Rogue One, but Book of Boba sounded like it would be dark as well and so far it hasn’t gone that far - Andor sounds like it will push the boundaries a lot more. That comment about being marketed at a more mature audience than other shows intrigues me the most. I doubt it’ll be R-rated but it sounds like this show will feel very different for sure.
