After Bigfoot has stolen the radioactive isotope and Nedlick uses his TLC to vanish, Nedlick's arm can be seem exiting the frame at lower left just after the jump cut.
When Steve is unconscious and the mechanical arm is slowly dropping on his legs, you can see Bigfoot's feet are actually very thick soled shoes. For a few seconds you can see a high heel like a 70's disco shoe.
Nedlick refers to Bigfoot as a stupid animal, when Bigfoot is actually a robot and not an animal.
