Why is it when a character in a film has grown large (such as Ant-Man in the Avengers and Civil War), do all their movements appear slowed down, as if they are moving through water?

Answer 1

Its due to their impulse during movement.

Small Animals like Ants can easily reorient their movement. Compared to their size they are verry fast and agile.
Big Animals like blue whales are slwo in their changing of direktion, they have a huge mass and therefore a change in the direction of movement is slowed down.
In Films this natural behaviour is simulated.
