Basically, the only modern studio consistently putting out stop motion animation movies, is Laika Studios. And yet, Laika has only had one financially successful movie, Coraline from 2009, while all their other movies have under performed.
However, Laika is currently led and owned by Travis Knight, son of Phil Knight, the owner of Nike. This has enabled Knight to continually bank roll Laika whenever they under perform, essentially making the entire stop motion animation film industry a nepo baby’s pet project.
That being said, this is actually a positive story, and reminiscent of how artists previously would be financially supported by wealthy benefactors.
For the other movies, while they dont meet Hollywood standards of success, they still succeeded. If you spend $60 mil employing people for 2 or 3 years, and are doing what you love, and it pays you back $60 mil to do it again, that’s success. Even with the flip in there, the others covered it. As long as they break even, it bankrolls the next movie.
