One thing amateur actors lack is technique. Sometimes trying to embed a foreign technique into a new actor can be a challenge. One of the most important techniques any actor must have is the innate ability to control time and space. A good actor can speed up time or slow time to a crawl. Speeding up is easy; slowing down is hard.
In a recent blog entry, I argued in the comments how time can be bent by the mind into slow motion in order to protect the body:
In the past, we have discussed here the phenomenon of time bending during accidents and emergencies as real time re-shapes to a crawl — I argue that slowing down of time is another brain protector that gives the body a chance to try to respond to, and then avoid, death or permanent damage. One inch here, a bend there, a twitch right there — can mean the difference between living and the forever darkness.
