To put it more bluntly, The Avengers series, Captain America series, Raytheon series and so on.
Basically, they are films invested and produced by Disney. Of course, it also includes the upcoming "Star Wars: The Last Jedi Knight" and the post-production "Star Wars: Korean solo". These are the strongest IP, and the film industry cannot do without fire.
