Spider-Man: Far From Home - What Does The Multiverse Mean For MCU?
4. The Spider-Verse
It'd be remiss to think that the multiverse concept would solely benefit Marvel because, lest we forget, this is a Sony movie too. They're the ones taking home the profits at the end of the day, and while having Spider-Man in the MCU definitely helps them, having him in a multiverse is even better.
Last year, Sony opened up the multiverse themselves with the brilliant Spider-Man: Into The Spider-Verse, which introduced web-slingers from a variety of different dimensions. What's to say now that one of those dimensions couldn't be the MCU? Or what about Venom, who is a Spider-Man character without a Spider-Man? Could that now be another alt-dimension off the MCU multiverse?
This goes both ways, really. Marvel and Sony are going to have to negotiate a new deal for Spidey soon, and it benefits both of them to have him in the MCU. But if there's also a means of Miles Morales appearing later down the line, introducing Oscorp, or having Tom Holland cameo in another Sony movie, then you can bet they'll be looking to take it, and the multiverse makes that a much easier proposition.
Of course, if things don't work out between Marvel and Sony, then the multiverse also offers a way out. It won't be that clean, of course, but Sony can simply bring Spidey over to one of their dimensions (say, the one with Morbius and Venom in it) and Marvel can either ignore it or reference he's gone to another dimension or some such (it'd be messy, but there's no good way to suddenly lose Spidey from the MCU). Let's just hope that doesn't happen, eh?
