Factual error: Towards the end of the movie, we see Dr. Challis hide amongst some boxes when running from Cochran's men. Challis then finds a phone on the wall and dials his ex-wife, attempting to warn her of Cochran's plans. When he dials her, he only pushes 5 buttons on the phone. Even without an area code in the United States, all phone numbers have always had 7 numbers.
Suggested correction: The entry says that Dr. Challis dials 5 numbers instead of a usual 7. Went to that scene in the movie and Dr. Challis did press 7 numbers. What made it look like 5 is him pressing a number or two twice.
