Revealing mistake: The way the pallbearers are effortlessly holding/carrying the casket (cupped palms underneath, sometimes not even touching, or just tips of fingers) is not possible. (00:15:27 - 00:15:55)
Continuity mistake: Kristin's suitcases are the same height and appear to be identical sizes, but one is smaller when she gets to Italy and has them stacked on a cart. (00:10:32 - 00:11:00)
Deliberate mistake: Kristin would not be physically able to hold Fabrizio from falling over the ledge using only one hand/arm (or even both). (01:30:22)
Revealing mistake: After Kristin tramples on the muffin, it should crumble/flatten, but it starts to inflate back into shape. (01:17:45)
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.
Factual error: Kristin meets Lorenzo at the airport. He asks for her number, which she gives him. Later when he calls her, her Mafia family take the phone and smash it to pieces while she's talking. They give her a new burner phone. They say they did a background check on Lorenzo. How? The family never met him at the airport, the only time she saw him. Further, when they meet for dinner (how she found him is another mystery), she shows him a picture of her son on the phone. How did a photo get on her new phone?
