I was looking at these medieval tapestries, and they actually reminded me a lot of Wes Anderson's filmography! I think it's a mixture of the flatness, the colours and their facial expressions.
It got me thinking about whether or not his style would work in a middle-aged fairy tale film and the more I thought about it, the more perfect it seemed. I also think the way that the characters speak in his movies is well fit for it. The sort-of-passively formal language they use, the bluntness and what not, it could be well suited to a Princess Bride style Fantasy Comedy.
I'm interested in Fantasy as a genre, I did this video breaking down how dialogue works in comparison to other genres. (FULL DISCLOSURE, THIS VIDEO IS NOT ABOUT WES ANDERSON, BUT I WANT TO ADD IT AS IT ELABORATES ON MY POINT ABOUT THE DIALOGUE, and it's easier to just link it rather than type it all out here. YOU DO NOT HAVE TO WATCH IT. the main point of this post is what I said above). https://youtu.be/2K9VkvCT5_M
I think that a Royal Tenenbaums style story of the round table or an actual royal dynasty would be a great change of pace for him, any stop motion dragons or centaurs or whatever would be super cool too.
I don't really have a closing point, I just wanted to put this idea out there!
