Other mistake: The scene where the king has directed his aides to issue "a firm denial of these accusations" makes little sense, since Alex has already officially and firmly confirmed their relationship from the White House press room. For the palace to announce that the son of the US president is lying would create diplomatic chaos between two very close allies and would not happen. (01:42:25)
Other mistake: When Adam Sandler calls his daughter on a video chat in the car with her friend, the picture of his daughter is not the same as when she is in the car. When they jump between her and him on the call, her hair and background are completely different than they are in the car. (00:23:17)
Other mistake: The minimal motions Olive makes with her marker on her "List for Santa" do not come anywhere near what is required for her to write "bring Grandma here for Christmas." (00:19:34)
Other mistake: In the Special Thanks section, Bobcat Goldthwait's name is misspelled as "Goldthwaite." (02:28:28)
Other mistake: The window looks closed, but even if the window is open, the woman ironing in her house across the parking lot would not be able to hear Jay and Maggie's argument from that distance, only muffled voices at best. (00:05:18 - 00:06:11)
Other mistake: Kristin takes a photo of her and Lorenzo and posts it to Instagram. A few moments later, her husband shows up and says he came to see what was going on because he saw her uploaded photo. She says it was only one photo. The photo was taken a few moments before. How did he get there so quickly all the way from the US? And came directly to where she was? Impossible.
