The Marvel Cinematic Universe took a bold step into a whole new world this Monday, with the trailer for Spider-Man: Far From Home confirming the existence of the 'multiverse' in live action. Jake Gyllenhaal's Quentin Beck (Mysterio) claims to hail from another world, like ours, only different.
The scene seems to take place just after Nick Fury takes Spider-Man from his European vacation. At a secret base, he introduces Peter Parker to Beck, who claims to hail from 'Earth-833'. Beck also confirms that the MCU is designated 'Earth-616', the name usually ascribed to the 'main' Marvel Universe from the comics.
While the significance of '616' won't be lost on Marvel fans, it is Earth-833 that deserves extra scrutiny. That particular world was only introduced a couple of years back, and featured a version of Spider-Man who was also Captain Britain - Spider-UK.
While Mysterio's true intentions are still yet to be determined, there were rumours a while back that Far From Home could potentially seed the introduction of Captain Britain into the MCU. The character is inextricably linked to the Marvel multiverse in the comics, and this latest hint follows an Avengers: Endgame Easter egg that seemingly confirmed the character's existence too.
It's a long shot granted, but parallel worlds mean parallel Spider-Men. Given Tom Holland is from the UK, could there be a moment in Spider-Verse where Peter Parker meets his 833 counterpart? Who knows - pretty much anything is possible at this stage, even if Mysterio isn't what he appears to be.
