Eisenstein’s favourite method was Intellectual montage, he would link people to animals like bears and owls. he did this because it was a silent film and he wanted people to start to have opinions on the different characters, by comparing them to animals.
this example is a fox, they chose a fox because he is meant to come across as sly and untrustworthy. this is a good example because foxes are known for being the “bad” character in films and known for not being very good.
another example of this, is the man as a monkey. they chose this because he is almost inhumanly and he is acting like a wild monkey, they chose to represent him as a monkey because he has wild limbs and he chops up things all unsteady.
