It’s worth noting that the Peter Parker established in Spider-Man: Homecoming becomes the superhero a couple years younger than Maguire’s.
On the other hand, Maguire is supposed to be around 17 or 18 when his origin story plays out in 2002’s Spider-Man, not to mention the actor was in his late 20s when he portrayed the teenager (Holland was around 20).
Holland’s Spidey is 15 when we meet him and he’s already been bitten by a radioactive spider and seen the loss of his beloved Uncle Ben.
