The overlooked Hyper-Carnivores

Most of you probably know what an Acrocanthosaurus, a Mapusaurus, an Oxalaia or a Zhuchengtyrannus are, they were all in the same size and ferocity range as some of the biggest guys out there like Rex or Spino, but just like many others, which i didn't list, they are hardly known at all by the general public, but why?

Except for the obvious reason,  which is that almost none of them are featured in famous dinosaur movies like Jurassic Park, etc., every fairly well-known Dinosaur represents a certain continent, for example, when you think of large european Carnivores, Allosaurus instantly comes into mind, in North America it's the same with Tyrannosaurus, almost nobody will know what an Acrocanthosaurus is. In South America, it's Giganotosaurus, most people have never heard of Mapusaurus or Tyrannotitan before. In Africa Spinosaurus and Charcharodontosaurus are the reason why nobody knows of Sauroniops and many others.

Which leads me to believe that the slightly smaller Dinosaurs are less well-known because they are "nothing special" in the eyes of the people that make movies and documentaries about Dinosaurs, because the public want's to see the biggest and baddest creatures out there, so a movie that's about a T.Rex is bound to be more famous than a movie that's about an Acrocantosaurus, which then means that the company that makes a movie about a T.Rex get's more cash than the company that made a movie about Acro, which in return means that the other company also want's to make a movie about a Dinosaur that's already famous and those less famous Dinosaurs are left in the dust.
