(Pause to imagine the dark future where every attractive young actor has to play Quicksilver.

TheX-Menfilms are more lively in their depiction of superpowers and tend to play fast and loose with narrative foundations.
Quicksilver helpfully microcosms those different styles.
So he’s a nice control group for exploring the superhero-movie tactics underpinningFuture PastandUltron.
InFuture Past, the character is introduced as “Peter,” a rascal kid living in the suburbs.
Compare that to Quicksilver inAvengers, who’s given a surplus of motivation.
Of course,UltronQuicksilver is never even referred to as Quicksilver; he’s “Pietro.”
(TheAvengersmovies generally downplay superhero names, not to mention the whole idea of secret identities.
TheX-Menmoviesmade a sport out of picking codenames.)
So there’s nothing inAge of Ultronthat comes even close toFuture Past’s big Quicksilver scene.
Bryan Singer hasn’t directed everyX-Menmovie, but he’s the defining creative voice of the series.
And the way he uses Quicksilver is typical of the X-franchise.
(See also: Nightcrawler inX2, who hasanothergreat showcase scene before disappearing for half the movie.)
In theAvengersmovies, characters have superpowers, but those powers are kind of beside the point.
(Thor hardly ever uses his hammer to control the weather; the hammer’s for hitting people.)
