Continuity mistake: When Mel Gibson is unwrapping the tarpaulin from his boat, there is less rope shown tied round it in early shots than there is in later ones.
Continuity mistake: When Kurt Russell and Michelle are having dinner in her restaurant, Michelle goes over to her counter to find an envelope with her name on it that is smeared from the rain leaking through the roof. Later she is shown opening that envelope and the writing is completely different, the name is positioned differently, and the name is smeared 3 times worse than before.
Continuity mistake: When Kurt Russell pulls into the police station (when Joanna is trying to get her chef out) he pulls up behind Joanna's car. After he helps Joanna and the chef, she gets in her car and drives off. Kurt's car has disappeared.
Chosen answer: It's not the sunglasses. It's the matches. Nick is acting as though he is coming closer to Joanna to get a pack of matches, which she then notices he already has. She realises that he is trying to eavesdrop on her conversation, and although she was previously buying his apology her demeanor changes drastically once she is finished with the phone call.
Oh my gosh, thank you! One of my favourite movies, yet I didn't get this scene.
