He’s Younger
Though it sometimes fluctuates a bit, Bruce Wayne is generally believed to be in his mid-to-late 20s whenever he first dons the cowl and cape. When it comes to the movie themselves, the filmmakers tend to follow the Caped Crusader whenever he’s in his 30s or, sometimes, even in his 40s, as he’s already established as Gotham’s shining hero — if often lurking in the shadows.
While Batman Begins followed our titular hero during his early days, we only catch a glimpse of his beginnings before we’re transported to his more established presence in The Dark Knight. With The Batman, we’ll get a chance to see a younger, more adaptable Batman in action, notably as he’s still fighting against his lack of experience and expertise to prove himself as Gotham’s newest detective. It’ll hopefully provide a more boyish, less established young crime fighter (as we’ll discuss more below).
