This article about the upcoming film Spider-Man: Brand New Day includes an interesting line:

Holland himself has wondered how long it will be before he ages out of the role

So I wondered: How old has Spidey been?

Tobey Maguire was 26, 29, and 31 for his 3 movies with Sam Raimi — and then, of course, 46 for his appearance in No Way Home.

Andrew Garfield was 28 and 30 for his two outings, and 38 for NWH.

Tom, though, started younger and has worked more. He first appeared in character in 2016’s Captain America: Civil War, when he was not quite 20. His subsequent films had him at 21, 21.9, 22.9, 23. and finally about 25 and a half for the most recent No Way Home. When Brand New Day drops this summer (his 7th film, and 4th as the title character), Holland will be 31.

That’s about as old as Tobey and Andrew were in their final appearances, so I can see why Tom might be worried — but the prior adaptations ran out of steam in the writers’ rooms, not because of a geriatric Peter Parker. By my lights, the MCU edition of the webslinger has more legs (ha ha) — plus, and not to put too fine a point on it, Holland has a far more youthful energy at 31 than either of his predecessors.

I dunno what Kevin Feige has on his private whiteboard; no further stand-alone Spider-man features have been announced, but it DOES seem likely that we’ll see Holland in Doomsday this December.
