Helen Sage
Helen Sage played the nurse of Dr. Brandt. Apparently this was her only film and she did a credible job of it.
I must point out that it would seem that she did not know how to drive a car as it appears to me that when she rolls up to the office it looks as if the car was pushed into the scene and she brakes pretty hard.
Later, when they are up at the invasion landing site, just before the Thor character clubs her, she is supposed to be driving but the driver -- barely seen -- looks to be a much taller person than she was.
