When Evie boards the plane to cross the Atlantic, she takes off in an aircraft with 4 engines and an upper deck. When then plane lands in England, it is a different aircraft with two engines and only a single deck.
When Evie helps the maids clean up the broken glass, her sculpture disappears momentarily and her cell phone (that she puts in her right pocket) appears in her left hand.
When Evie and Walt are lying down talking about what they want in life, Walt's head goes from being propped up on his hands at the nape of his neck to being propped up on his hands over his ears in between shots.
