Ana uses her tablet computer to read a newspaper article when she is informed that the press have reported Jack's break-in and attempted kidnapping. She places her finger on the screen twice to scroll the screen down, but neither the article or the screen icons visible move.
Ana is able to withdraw $5 million in cash from her bank in a matter of minutes, but no bank routinely keeps that much cash on hand.
Early in the film, after Jack Hyde goes on the run, Christian is told that Jack hasn't been seen in a month. Later in the film, when Ana is being interviewed by police, she states that Jack used to be her boss but was fired about three weeks ago. However, he could have been fired "in absentia".
At 1:01:16 in the red room, Christian tells Ana to bring it from top drawer on her right, but it's actually left for her. Another goof is that Ana actually goes to her left.
