The band gets back together in Joss Whedon’s Avengers: Age of Ultron, which is now playing everywhere throughout the Multiverse.
My review is at PopMatters:
A sturdy piece of inessential workmanship, The Avengers: Age of Ultron begins where it ends, with Joss Whedon shooting the works. In “Sokovia,” another made-up slice of the Balkans, the Avengers are assaulting a mountain fortress controlled by Hydra. That would be the world-spanning network of bad dudes discovered at the end of the last Captain America to have infiltrated the S.H.I.E.L.D. network. It’s not entirely clear what their motivations are besides being evil. Perhaps they’re ticked off at not having quite as cool a name as Cobra Command…
Here’s the trailer, in case you haven’t already seen it two dozen times:
