User blog comment:Mark4518/X-Men’ Producer Would Love An ‘Avengers’ Movie Crossover/@comment-2198188-20130220175634

A better idea to have the universes, all three of them, use Spidey. We can have Spidey in an Avengers movie, making the Amazing Spider-Man part of the MCU. But then have Spidey crossover with FF or X-Men. It creates the idea that the three universes are one universe. And then think of minor crossovers. In other words we use Spidey as the bridge to connect the 3 movie universes. It allows some crossovers.
