Robert Bakker says that King Kong wouldn’t be able to get enough to eat.
There are more serious issues than that. Even if he could get enough to eat, for a body with that much mass to move that fast, the heat generated would be much greater than could be radiated out through the skin (mass goes up as the cube of the major dimension, whereas surface area only goes up as the square), particularly through that fur coat, so he’d cook from the inside if he maintained the kind of activity levels presumably depicted. Also, he wouldn’t be able to maintain his own weight on those (relatively) spindly legs, once scaled up to that size–they’d splinter like toothpicks.
No point in seeing the movie, folks–it’s just not realistic…
