The beginning of the movie was set on Thursday, the day after Jim died, and Bridgette's face was just fine. Later in the movie, on Saturday, Bridgette was at the funeral with cuts and stitches on her face. Then, the movie goes back to Tuesday, the day before Jim died, and they show Bridgette running into the glass door and cutting her face. So if it happened on Tuesday, the first scene of the movie (Thursday) should have shown the cuts on her face.
Kate Nelligan plays Sandra Bullock's mother in the movie, even though in real life she's only 13 years older than Bullock.
