Spolier

It's strange that when watching the dailies, no one said "Hey when Megan Fox falls through the ice and makes it out in the end, shouldn't she at least be shivering or acting like its cold since hypothermia would of started?" Did the director just say "screw it" or "she does not have the acting ability to pull that off" or was it just rushing to get the movie done and thinking no one would care?
