Factual error: At the onset of the baseball game, take a look at the Angel's catcher as Mariner Jay Johnstone steps up to bat. You will see he is wearing just a standard baseball hat under his catcher's helmet. MLB rules requires some form of certified (protective inside and out) plastic helmet for catchers, and thus this would not be allowed.
Factual error: In the scene where Frank is in the car, and the Doctor shoots at them, the windshield breaks right out and pieces fly all over Stephanie (the driver). This could only happen with a window made of something like plate glass. All windshields since before the 1940's have been made of a glass that will not break as a plate glass window does, so the bullet should go through the glass and just leave a little hole with cracks all around it.
Factual error: Frank hits some garbage cans with his car and the air bags deploy. He gets out of the car and another air bag deploys underneath the steering column and pushes up on the automatic gear shifter, which presumably makes the car start rolling. If the engine is off, a car will roll with the shifter in any position except park. Therefore, the shifter had to be in park when he got out, so pushing up on the shifter would not make it roll.
