Why is it portrayed in movies that if you get bigger to smaller people you look like you’re moving slowly

Question

Like antman in civil war, from our point of view he looks like he’s moving slowly.
So from his view do smaller people look like they are moving faster?

Edit: and is this only in films or would this be true to life?

In: Physics

Answer 1

It’s not entirely relevant, but an enlarged person should theoretically react slower than normal, because nerve signals have finite travel speed. The brain will probably adapt and compensate the “lag” somewhat given enough time though.
