Factual error: In the second last scene, when Rachel is leaving Singapore for New York, Nick went onboard to propose, and convinced her to stay in Singapore for one more night. However, that's not possible in Singapore as there are strict laws stating that those that enter the departure area must have a boarding pass, with the purpose of leaving the country. Those that have a boarding pass but have no intention to depart the country will be prosecuted, and in 2018 40 people were arrested for various reasons, such as sending a friend off and meeting their idols, etc.
Continuity mistake: When Ana and Christian are having sex on the dining room table, she drops Christian's pants below his butt. Scene cuts and Christian's back is shown, with his pants above his butt. Then cuts back and they're below again. (00:54:40 - 00:56:50)
Factual error: The plane used in the film to take Juliet back to London towards the end of the film is a replica of a Dakota C-47. She is painted with black and white "invasion stripes" on both the upper and lower surfaces of the wings - approved in May these were only widely put into use for D-Day in June 1944. After one month the upper surface stripes were ordered removed, and by the end of 1944 they were ordered completely removed. By 1946 when the film is set they would have been long gone from any serving aircraft still flying.Andrew Upton
Continuity mistake: After performing 'surgery' on the bear, Tasha goes visit another one of her little patients. Before she sets foot in the room bickering with Jeff you can see her hair flows left and right of her colourful pin on the coat. Inside the room, her hair is just on one side, switches side, and it stays that way till she exits the room, when once more there is a visible change at the cut. (00:03:30)Sammo
Continuity mistake: Kevin and his daughter handed the invite for the dream-like contest to the protagonist. He shoos her away saying "Liv, don't you need some milk with that cookie?" His arms are crossed behind his back. Next shot and she is walking away from him with his hands crossed in front of his crotch. (00:02:20)Sammo
