So i've been hearing Sony is worried about how far behind they are for VFX on this movie (with VFX artists now working 7 days a week to get it done). Between The Eternals low RT Score and the extremely low overseas box office, I think it's reasonable to question if they push this film from it's current date to March where Multiverse of Madness was previously slated to be released.
All you have to do is look at Venom 2's overseas box office to see the issues... It opened higher domestically than the first movie in 2018, but overall is still $20M+ behind where it closed domestically and will be lucky to finish with the same amount and overseas, it's only made $205.4M compared to 2018's $642.5M. Venom 2 never got a China release, where Venom took home $269M in 2018. Sony execs have to be freaking out about that considering that's where Spider-man related movie's tend to clean up (Homecoming grabbed $116.2M in and Far From Home took $198.9). Other regions slacking at the box office doesn't help either.
No Time To Die is a perfect example - It has a little over $600M Worldwide after three weeks and getting and release in China. That puts it past Quantum of Solace and Casino Royal, but also puts it almost $300M beind Sprectre and close to $500M behind Skyfall.
