This is a response from your sympathetic nervous system, a part of your
nervous system that is not under your direct control. When your senses take in the scary movie that your brain perceives as being
threatening, the system produces the "flight or flight" (metaphor) response. Nervous
system signals are sent out to certain glands that release hormones into your blood stream.
One of the major hormones that is released by the adrenal glands in
response to these signals is adrenaline.
Adrenaline courses through your blood stream and affects the
functioning of a large number of organs and tissues, including the
heart and lungs. So you jump like you are about to run but then you remember it is just a movie so you don't run. Hope that helps. =)
