A senior character animator for Spider-Man: Across the Spider-Verse explains that splitting the film into two gives the ambitious story breathing room. SpiderMan AcrossTheSpiderVerse SpiderManAcrossTheSpiderVerse Sony Marvel
\nWe knew that Sony was going to make a sequel to Spider-Man: Into the Spider-Verse, and in December 2021, we found out that the film they were making was so big that it needed to be split into two films. At one point, Spider-Man: Across the Spider-Verse had a 'part one' and 'part two' attached, but they eventually dropped the parts and renamed the third movie to Spider-Man: Beyond the Spider-Verse.
We'll have to see,' explained Santos. 'It was a really ambitious movie, and at the beginning, it was insanely ambitious, versus what it is now. It's still super ambitious, but it was like trying to fit two movies into one essentially. But now things can breathe a little bit more.'\nAgain, Sony could have easily phoned this sequel in, and it probably would have done just fine at the box office, but the fact that they are willing to go the extra mile really speaks volumes.
