Factual errors: When Samantha Taylor uses the operator to phone home, she asks for a number in the 275 prefix in LA (which was all 213 area code at the time). Although George Webber home is clearly located in Malibu, the 275 prefix in the late 70s was located in Beverly Hills. Additionally, the film doesn't use the now standard convention of unassigned "555" prefix phone numbers, and gives an entire seven digit number - 275-0187.
