think what you want, say what you will, but Spidey-Verse versus Peter Jackson's Mortal Engines should see 2 40M+ OW's duking it out in December.
if you were to look at a magazine highlighting Winter's movies, hyperactive fan-driven kids might come up with the same conclusion.
As an original movie, and since it has been so long since King Kong, I expect Mortal Engines to out-perform King Kong.
