Spider-Man: Far From Home is the 23rd feature film in the Marvel Cinematic Universe and the final entry in its Infinity Saga. It is the 11th and final film in the MCU's Phase Three, even though everybody thought it'd probably be the first part of Phase Four, and now nobody really knows what Phase Four will start with.
I haven't entirely understood anything I've written so far, but I do get this bit: There won't be another Marvel movie for ten whole months -- all the way until next May.
Far From Home is the eighth Spider-Man movie across four different series, and it's at least the third one the Nose has covered (following Homecoming and Into the Spider-Verse).
