When Ana is getting ready for the masquerade ball, she's dressed in garters, stockings, and a bustier. Christian is already in his tux. At the ball, Christian undresses her and her only undergarment is a thong.
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.
During the dance at their wedding reception the barrette in Ana's hair moves from right to left and back to right...
When Anastasia is speaking with Liz Morgan in her office early in the film, Ashleigh LaThrop, the actress who plays Hannah, can be seen standing just outside of the door waiting for her queue to walk in and greet Anastasia. But this could simply be because she was respectfully awaiting her turn.
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. Correcting data: yes, the cabinet is to her left but when she gets to the cabinet she opens the drawer on the RIGHT. Christian's exact words were "Top drawer on the right" the insinuation is that the area to her physical left didn't have any cabinetry. and this was actually at 1:04:26.
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.
When Christian is standing by Ana's hospital bed, she wakes up and he stars to cry, but it can be seen that no tears are actually coming from his eyes, revealing the use of fake tears.
The morning after Ana is attacked in the penthouse, she is back at work, and her assistant comes in to show her the story on her iPad. Ana moves her finger on the screen like she's scrolling through the story but nothing on the page moves.
Right after the wedding, they pull up to the private jet in the car, and Ana looks out the window at the plane and says "You own this?" After being together as long as they have been, not likely that she would question him owning a jet. She knows about his helicopter and everything else he owns.
Looks like editing flipped the wedding dance scene.
When Christian is in Ana's office to complain about her not changing her name, the actor Jamie Dornan loses his American accent when he says "You got this through hard work and talent."
When Christian and Ana are leaving the empty grand house, Jamie Dornan loses his American accent when telling Ana: "You can handle her, you can handle this".
