Visible crew/equipment: As Sarah starts to slide to a stop as she sees the Terminator, you can see the shadow of the camera on her left shoulder and arm.
Trivia: When the biker stubs his cigar out on the Terminator's chest, Arnie's protection was only a small block and piece of fake skin the size of a dime, so the actor had to be very careful to avoid burning him.
Continuity mistake: When Sarah Connor throws the keys to a male orderly to distract him, Dr. Silberman is standing right behind him. Two shots later, we see the doctor several feet away. The time lapse between the two shots was only one or two seconds. (00:56:25)






Answer: In addition, another deleted scene shows that the T-1000 was damaged by being frozen and thawed and was having difficulty maintaining form. He wanted to be sure he wouldn't mess it up.

What's especially odd about the scene is that both examples we gave to help answer this question were actually deleted from the original release. When I first saw this movie in the theater when it was released I had the exact same question, it wasn't until I saw the Special Edition with the deleted scenes reinserted that it made sense.
