Corrected entry: When Jodie Foster sets the propane alight, she tells her daughter to get under the fireproof blanket, and then gets under one herself. However, she only covers the lower half of her body, so if the propane had set fire to the rest of the room hiding under the blankets would have been pretty pointless.
Corrected entry: When the mother and daughter were in the panic room and the daughter was going through the containers you see M.R.E.'s (Meals Ready to Eat) in there. Later in the movie, the daughter needs sugar to keep up her sugar level but they couldn't find anything sweet. In an M.R.E. there is chocolate in each one. She would have known this because she opens one up which is laying on the ground as the mother is searching for something for her daughter.
Corrected entry: When the two remaining thieves are in the Panic Room with the young girl about to break into the safe, one pulls back the carpet to reveal the safe. The shot changes and when it changes back, he pulls back the same bit of carpet again.
Corrected entry: The first time you see Jodie Foster look at the skylight, there's rain dripping down the side of the glass. Later, when the robbers look at the skylight, there are sounds of rain, yet no drips on the glass. Then, not too long after, Raul looks outside where you can see the rain and people walk by with umbrellas, so it is still raining.
Corrected entry: Throughout the film Dwight Yokam is wearing a ski mask. In the beginning it has an opening at the nose for easier breathing, but at the end it does not and has somewhat different form.
Corrected entry: When they are going to gas the girls with propane they get a garden hose to hook it up. When they do so they stick one metal end into the duct and the other over the valve to the tank. Why does Dwight Yoakam cut the hose in half with a knife? Wouldn't this just let the gas leak into the room that they are in?
Corrected entry: In the meal scene, the girl is seen drinking a coke from a red can. A diabetic would never drink full-sugar coke, they would have a diet one, which comes in a silver or pale blue can.
Corrected entry: In one scene, one of the intruders gets his hand caught in the door of the panic room as it slams shut. However, it is shown earlier in the film that the panic room door is equipped with motion sensors to avoid just such an accident.
