Corrected entry: When Satch tells John for the first time that his mother is now a Nightingale victim John is surprised and has no idea. But he should, he got all new memories for everything that changed so he should have memories of his mom being a victim and investigating it.
Corrected entry: In the scene where Dennis Quaid by accident sets the desk on fire, we see how the burn mark appears on the desk in 1999. But why is it still hot and smoking 30 years after? Same goes for the writing with the soldering iron. In comparison, the wallet has got signs of being 30 years old when the son finds it.
Correction: Considering how everything else in this movie operates, it's not a stretch that this happens the way it does. You must remember, things in 1969 are happening at the same time in 1999 in this film. There are two timelines happening at the same time.
Factual error: A ham radio requires the person to hold down the button while talking. Numerous times in the movie they are talking without pushing the button.
Suggested correction: This is actually subtly addressed in the film. The magic which allows the radio to work across time also allows the two men to speak without pressing the button. There is a moment where Frank wonders what is going on with the radio and presses the button a few times to talk but then notices that he doesn't have to press the button to be heard.
If that was true, then it wouldn't make sense for them to continue to show Frank and John hitting the squawk bar throughout the film.
That is a separate issue. The mistake entry states that you need to hold the button to talk on a ham radio, which is true, but the magic ham radio in the film doesn't require it. If the actors continue to occasionally press the button that could be considered a character mistake but it could also simply be a force of habit by the characters.
Correction: He does have memories of working the case, but he is confused because he also has memories of his mother being alive. The same thing happens with the memories of his father dying in a fire but then surviving that fire later. John describes it as confusing because he has both sets of memories.
