the New York Times hailed T. rex as "the most formidable fighting animal of which there is any record whatever," the "king of all kings in the domain of animal life," "the absolute warlord of the earth," and a "royal man-eater of the jungle." In 1906, Tyrannosaurus was dubbed the "prize fighter of antiquity" and the "Last of the Great Reptiles and the King of Them All." In 1927, Charles R. Knight painted a mural incorporating Tyrannosaurus facing a Triceratops in the Field Museum of Natural History, establishing the two dinosaurs as enemies in popular thought; paleontologist Phil Currie cites this mural as one of his inspirations to study dinosaurs. Bakker said of the imagined rivalry between Tyrannosaurus and Triceratops, "No matchup between predator and prey has ever been more dramatic. It's somehow fitting that those two massive antagonists lived out their co-evolutionary belligerence through the very last days of the very last epoch of the Age of Dinosaurs." Since then, popular culture has consistently depicted Tyrannosaurs as "King of the Dinosaurs" for decades. Portrayals have ranged from serving as an antagonist against whom human heroes could test their courage to an awe inspiring symbol of power, analogous to the lion's depiction as "King of the Beasts". According to paleontologist and museum curator Mark Norell, Barnum Brown successor at the American Museum of Natural History, Tyrannosaurus rex, "continues to be a subject of fascination, a popular icon, and probably the first dinosaur name imprinted in the minds of children globally. Besides all this, it is the inspiration for budding paleontologists worldwide. Long may the king reign." Film appearancesTyrannosaurus rex has played a major role in many films, starting in 1918 with The Ghost of Slumber Mountain, written and directed by stop motion special effects pioneer Willis O'Brien. The Ghost of Slumber Mountain is also, and most likely, the first film showing Tyrannosaurus facing Triceratops. However, while Ghost was the first of O'Brien's works to feature the dinosaur it was not the last time he would use the dinosaur, using it again in 1925, with the classic adaptation of Arthur Conan Doyle's novel The Lost World. Tyrannosaurus fossils were not so famous at the time of the publication of the novel (1912), and the only main villain dinosaur in the book was Allosaurus, with no appearance of Tyrannosaurus, but this 1925 film featured Tyrannosaurus anyway, for a more dramatic and spectacular
