Goofs

(at around 1 min) An Indian policeman wearing a red headband is seen directing traffic on the left side of the screen. When they park the car, the same Indian policeman has magically moved to the right side of the screen.

When Mak Tai Tai approaches the coffee shop, she pauses in front of the door to look around. In the next scene, she is about 6 feet to the right of the door, and has to walk back toward it.

The story ends with Mr. Yee and Wong picking up the ring just after the mahjong game from the opening scene. During this game one of the ladies mentions a ring with a gemstone as large as an egg. While choosing the gem for the ring earlier in the story Wong refers to this remark which clearly takes place later on in the story.

At the beginning, when Mr. Yee is being driven from his office to his home, the position of the parked windshield wiper blades shifts from scene to scene although it is not raining.

When the jeweler, Khalid Saiduddin, presents the finished ring to Mak Tai Tai and Mr. Yee, he shows it to them in a distinctive trademark octagonal red Cartier box. When he opens it, the shot attempts to hide the Cartier name inside the box, but the edge of it can be seen.

In the café scene where Mak Tai Tai is calling her comrades the ringer heard through the phone both times is a modern ringer, which wasn't used until the 1970s/early 1980s.

The London Taxi seen is the FX4 Fairway which wasn't introduced until 1959.

In the opening scenes in Shanghai, Wong is driven in Mrs Yee's Buick, which must be a 1942 model. A "gunsight" hood ornament is clearly seen. That ornament was not used until 1948. Also, the grille of the car changes from one with bars overlapping the front bumper to one with the bars entirely enclosed. The 1942 Buick did not have bars that overlapped the bumper.
