Continuity mistake: When Frances leaves her house she takes the blue vase. Only boxes of books were moved, the vase was seen on a desk at camp Divorce, however when the boxes of books arrived in Italy and she opened one, she took the vase out.
Continuity mistake: Frances finds and takes home a kitten when she first meets Marcello. Months later, when Marcello comes to the house to visit Frances, the kitten has not grown a bit.
Continuity mistake: The first time Katherine is seen eating an ice cream cone outside, in Cortona with Frances, the ice cream changes in size and shape - not in the way one would expect, but rather haphazardly - as well as the melting around the cone, as the camera switches angle giving alternating POV between the two characters.
Continuity mistake: When Frances is 'spherically' pulling ivy from the outside walls of her villa, she drops a branch behind her just as she see the snake and says, "Oh, my God." The shot changes from her face to the snake slithering over a window sill into her kitchen. As this shot pulls back and moves up to show more of Frances, we see that she now, once again, has a large branch in her hand.
Continuity mistake: When Frances is cleaning the bedroom when she first moves into the villa, there is a scorpion on the drapes that she smacks with a shoe. The scorpion falls, next shot it is back on the drapes.
Continuity mistake: After Signor Martini tries to find the snake in Frances' house he lights the stove with a match. He then places the match box on top of the stove with the long side of the box facing the camera. In the next several shots the box turns to the narrow side facing front and then back again.
