Homages to those famous fight scenes from King Kong
Ever since King Kong brawled against several prehistoric monsters in his 1933 debut, filmmakers (and other creators) have found the image of a giant ape fighting a vicious dinosaur too iconic, symbolic, and just plain awesome to resist. As a result, dozens of homages to the scene have sprung up over the years, as well as variations on its imagery and themes. The fight itself also makes popular stock footage if a scene calls for a character to watch a cheesy older movie. The scene can also be deeply symbolic, as it calls back to the mammals' supplanting of reptiles as the dominant animal class on Earth following the K-T extinction (especially if the ape wins, as it often does), to which humanity owes its existence. A clear subtrope of Cool Versus Awesome.
