Comic book movies are a funny thing. Because before the introduction of serialized storytelling and giant franchises with the Marvel Cinematic Universe, superhero flicks would typically be standalone films that operated separately from other installments in the genre. As such, there are multiple version of certain characters, while some actors have played quite a few superheroes in various films. Chris Evans played both the Human Torch in The Fantastic Four films and currently stars as Captain America in the MCU. Ryan Reynolds was DC's Green Lantern before stepping into Deadpool's shoes. And while Michael Keaton is playing the villainous Vulture in Spider-Man: Homecoming, he has the distinction of playing Batman long before Ben Affleck or Christian Bale. Now it appears that Keaton wanted to make sure the newcomers realized who wore the cowl before it was cool.
