Movies that did not get merch until after the fact

Many movies have merch on the shelves in time for the movie, since that's when demand will be at its highest, but sometimes the movie was not expected to be a big hit so no merch or not enough merch was made, so even though there is demand, there isn't any supply to meet that demand. And due to how long production takes the merch might not be ready for several months or over a year.

You can see this with K-Pop Demon Hunters. Not only did the studios not believe in the movie which is why it went to Netflix, toy companies saw no potential in it either so no toyline was made. Then it became one of the biggest movies of the year, and companies were left scrambling to meet the sudden unexpected demand, it's only recently that Mattel is finally putting out toys, up until now there was just shirts and other low-effort merch as well as lots of bootlegs.

This was also infamously the case with original Star Wars. It too was an unexpected hit, most toy companies refused George Lucas' offers, and even though Lucas managed to make a deal with Kenner, due to how late it happened and how long production takes the toys weren't supposed to come out until many months later. Kenner didn't have any action figures or playsets in time for Christmas, so they literally sold people an empty box with mail certificates to get your toys later.

And another strange case is when the movie has merch, but not for certain characters because they weren't expected to be popular. For example, Disney made several toys for Encanto, but they did not expect the character of Luisa to be popular, they thought girls would like Isabela more, so she didn't get as much initially.

So what other movies didn't get merch until later due to them being unexpected hits or somebody simply dropping the ball? Or what characters did not get merch until later?
