watch after the shuttle with AJ (Ben Affleck)crashes. He goes into the main shuttle area to find Oscar dead. If you watch closely, as AJ is holding him and crying,you see a flash of light and Oscar's eyes move. His eyes not only move once but a couple of times. Isn't he suppose to be dead?
Actually people still move slightly even after death. I don't remember the exact medical name for this, but it has to do with muscles an how they're flexed at time of death, and then they unflex creating movement. I doubt the actor was trying to imitate this, he probably did just move accidentally, but actually any slipup regarding dead people moving can be crossed away, and explained.
Isn't rigor mortis when a dead body stops recieving oxygen and the muscles develop deposits of lactose (or something like that), so they get all stiff and stop moving?
Well at least he/she was accurate with the name blondie. Rigor Mortis doesn't take 20 min (the approx time after death when the crash happened) Nik is right about twitching after death.
you have to remember that it is the movies, and things like that are going to happen. Actors are human also! So unless you were looking for that, (i know I wasn't), you wouldn't have noticed that!
