Corrected entry: When Danny is trying to convince Slater that he is in a movie during the Blockbuster scene, Slater states that everyone in LA has a phone number that starts with 555. Danny says that there can only be 9,999 phone numbers in the city with 8 million people. However, he forgot to take into account the number 555-0000 which would make 10,000 total numbers available instead of 9,999.
Corrected entry: In the scene where Arnold crashes into the taxi cab, he says 'this is a 1989 Mercury Sable, standard driver's side airbag.' An airbag was not available on that model until 1990.
