Sorry for sounding like a broken record but Spider-Man: Into the Spider-Verse is a really good movie and everyone should see it. The movie does a great job balancing the characterization of several key characters whilst also being fun and action-packed, with too many highlights to name. Simply put, Marvel Studios (and DC, and the people making those Godzilla films) have a lot to learn from this movie.
Fans of the Spider-Verse comic book might be a bit disappointed at the lack of other alternate Spider-Men but that's what a sequel is for. However, those fans will probably be happy to know that there was an Australian Spider-Man that was canned before release because they were past the pre-production stage by the time it was suggested.
Why should fans be happy over the lack of Australian representation? Because the character would have been killed off quickly as a joke that would also add stakes to the film. It's a good thing this Spidey wasn't added.
Here's what Rodney Rothman told CinemaBlend about the Australian Spider-Man:
"We created an Australian Spider-Man. He showed up with the other Spiders, and he said he was 24 hours ahead, and then he glitched to death. So everyone was going to be like, 'Oh, it's going to be 24 hours.' That was the official ticking clock."
There wasn't a set time limit for the character's glitching out in the final cut. All we knew is that the alternate Spiders had to get home eventually or they would die. Sometimes, that's enough.
Spider-Man: Into the Spider-Verse is now showing in theaters.
