Revealing mistake: Near the end of the film, Meryl Streep and Alec Baldwin are sitting on a lawn swing. The number of chains supporting the swing varies between shots. Sometimes the back stay is a single chain and sometimes it is a double chain.
Continuity mistake: During the bath scene where Jane is in the tub and Jake is sitting there talking, the candle on the window sill changes location. In the close up shots the candle and mug on the window sill are right next to one another. In the wide shots, the candle is towards the middle of the window.dnwde
