In the past years, the presence of comic book characters in the movies has been very stable; the Marvel and DC superheroes have been very busy keeping the movie houses full, which has maintained a whole system that viewers can easily identify and recognize. It's within this setting that some of the actors have even managed to take on different roles and work in both comic book companies.
One of the notorious cases is Ryan Reynolds, who played Hal Jordan in the 2011 lamp project, a DC film that failed commercially and critically, one of the biggest superhero movie flops at the time. The movie lacked a convincing tone and came to an end quickly. A few years later, Reynolds being with Deadpool in the company of Marvel produced a new direction for him; he built a character that drew very much on his own direct and sarcastic style.
Ben Affleck traveled the opposite route; he was after many others they had picked before it and challenged by generically released Daredevil when the genre did not yet have a standard for-story-narrative-universe-structure and picked as Batman in the DC - He could be become perhaps an angry more jaded and less idealized Bruce Wayne along with a more intense though dark narrative approach not only based on Snyder's style but even on some famous Bat comics.
J.K. Simmons molds his facial features to those of J. Jonah Jameson in Sam Raimi's Spider-Man films. So identifiable is this role that he switched back into the Marvel Cinematic Universe with it. Meanwhile, the actor played Commissioner Jim Gordon in Justice League, thus traversing from one universe to the other without lowering the impact of his screen presence.
Christian Bale was in the Batman trilogy by Christopher Nolan and helped to re-characterize the superhero realistically, to the point where he won over some skeptics and was one of the most acclaimed actors behind the Dark Knight. Then he took on the role of a god Slayer, Gorr, in Thor: Love and Thunder, a character choice that was the very opposite of the classic superhero. Michael Keato
