So I watch a rather large amount of movies, you could say too many but then you'd be wrong and rude, don't question how I live my life. Essentially what I've realized in my long and illustrious movie viewing career is that nothing in the history of cinema seems to understand how physics work. What has come to bother me more than anything though is the giant movie monster, recently seen in pacific rim being punched in the face by an equally giant robot, these disturbingly large creatures are not disturbing because of their size but because of the physical implausibility of their existence. When objects grow larger even maintaining the same shape mass grows at an exponential rate so that giant 40 ft tall women is gonna have even larger reasons to be self conscious and of more concern dead. You see as her mass grew at an exponential rate the density of her bones and therefore structural integrity did not. (It'd be akin to building a skyscraper sized building with the wood used in your small shed it's just dumb engineering and physics). So tragically for the giant movie monster woman the force required for her to gain any sort of velocity to move would shatter her bones in what is presumably a painful incident. The force due to gravity itself would probably being crippling, i doubt the standard design of a circulatory system is capable of creating enough force to travel up such a height against gravity. Essentially a giant movie monster would live an incredibly painful and brief life if the standard laws of physics were to ever appear within the world of cinema.
