The reviews are in for X-Men: Days of Future Past, and they are almost unanimously over-the-top positive (um, #sorryaboutit but we beg to differ). Whatever the case, everyone would agree that this caper’s shining moment arrives—and leaves all too prematurely—with Peter Maximoff, the man who becomes Quicksilver. The sequences in which this mutant displays his power evoke the spirit of the first films, and even deeper, bring forth what the superhero genre is all about: watching a seemingly ordinary (or sometimes not so ordinary) person display extraordinary talents or traits, and how that makes him or her different.

Specifically, the sequence in which Quicksilver uses his super-speed to help break Magneto out of prison at the Pentagon is killer (we don’t want to say too much, but Magneto is a significant character to Quicksilver). And the soundtrack—Jim Croce’s “If I Could Save Time in a Bottle”—is the cherry on the cake.

And now, the crazy curveball that makes Quicksilver so noteworthy: He was also featured in the post-credits scene of Captain America: The Winter Soldier last month, alongside The Scarlet Witch, and will be part of the core cast in Avengers 2: Age of Ultron. But this crossover isn’t as seamless as one would hope, because of an interesting casting conundrum. In X-Men: DOFP, the speedy character is played (with awkward aplomb, we might add) by Evan Peters (of American Horror Story), while in the Cap America/Avengers universe Quicksilver is portrayed by Peters’ Kickass co-star Aaron Taylor Johnson (currently on view in Godzilla as well). We wonder if these two co-stars have gone out for drinks to discuss playing the same character in parallel ginormous superhero franchises.

But what would this mean for an actual cinematic crossover between the X-Men and the Avengers? Would that be just too many superheroes? (Is there such a thing?)
