Uh, yes. It's MGM. They have nothing else that's this big - everything else coming is indie and prestige/awards releases, this film was meant to cover a lot for them - they already ended up delaying their big awards contender Respect (Aretha Franklin biopic) because they didn't have the money from Bond to do a campaign. And they've already blown their load twice marketing spend wise. And they're up for sale now too.
Also UK cinemas don't look to be able to reopen until May at this point, that's the latest indication re: hospitality in this current lockdown, which will only begin to ease up when enough of the most vulnerable are vaccinated, with now the latest timeline is every UK adult being offered it by the end of the summer. At the current rate timelines appear to be very similar Stateside too, and in continental Europe. All the big stuff that can't have PVOD or streaming as a cushion like the Warner Bros/HBO Max stuff, is gonna be pushed.
