Future DC or Marvel movies like Joker?
The director/writer said he as a general rule doesn't like superhero movies because they are too "loud" (and while not a superhero film, the original director of the Dwayne Johnson version of Journey to the Center of the Earth pulled out because it felt too much of a rollercoaster ride).
Joker showed that it is possible to make a successful movie that is calmer and less Michael Bay. Simultaneously visual effects are getting both better and cheaper. So why not combine them? A film that require CGI and performance capture to explore a certain comic title, but which is more about the characters than explosions, car chases, alien invasions, epic battles and shooting scenes. Ghost Rider for instance, or Solomon Grundy, Hannibal King (from the 70s), Mister Miracle's life on Apokolips, Etrigan the Demon, Machine Man, Creeper or even Jack O'Lantern (the way he is portrayed in Amazing Spider-Man issues 234, 235 and 236). There are plenty of both major and minor characters to choose from if DC and Marvel should want to explore a different approach. That would actually be closer to the comics I grew up reading that the movies based on them.
