Revealing mistake: In the first scene at the beach, where Ali carries Stephanie to the water, you can see the shadow of her legs, despite her legs being amputated. (00:41:25)
Suggested correction: Can you? You can see his shadow for sure, but I don't see her shadow cast on anything. I was looking for this mistake on Prime - I added the timecode for the scene too (41:25) in case someone wants to check out and maybe submit a screenshot, too - but I personally can't see it.

Factual error: The VW Bug that the belfry falls on is a later model than 1965 when the movie is set. The larger tail light with yellow on the lens seen on the VW in the movie didn't come along until 1968. The one in the movie may even be of early 70's vintage.
Other mistake: At the end of the movie when all the new dads are hanging out, Davis misses catching his beer and it hits Jordan in the face. All the dads run to the edge of the stairs no longer carrying any of their babies from a few seconds earlier.
Continuity mistake: In the scene where Dodge and Penny enters Olivia's last known residence, Penny one of the door windows. She then gets access to the door lock on the inside and she opens the door. As Penny and Dodge enters, it is visible that the window is broken. This is shown both in the first and second shot. At the third shot it is easily noticeable that the same window behind them has been magically repaired, and is in a normal, unbroken condition. The fourth shot shows that the window is again broken. (01:03:45)
Continuity mistake: After Dave leaves the party that he and his friends go to after the movies, he's driving in the car.

Continuity mistake: In the very beginning, the truck that hits the vehicle does so from straight behind. However, when they pan out, someone the truck is perpendicular to the crashed car. The snow tracks don't show the car that was hit swerving, and there aren't any tracks to show that the truck reversed either.
Factual error: In one scene Drew Barrymore stands in from of a political world map, showing the political borders as of today. You can see the successor countries of the Soviet Union in that map. But the plot plays back in 1988, with the Soviet Union still alive.
Other mistake: When Christine is shot near the end of the film, there's no blood on her dress or the Phantom's hands.
