Visible crew/equipment: Crew member's head is visible in the mirror at the back of the room, when Evelyn is playing with a sword. The head in the reflection turns and he smiles, as she jumps off the desk and moves out of frame. (00:16:00)

Revealing mistake: When Evie and Jonathan jump out of the truck before it crashes (during the chase scene right after the Emperor is brought back), as Evie lands on the ground you can see the outline of the kneepads she is wearing beneath her stockings. You can also get a brief glimpse of the stunt-woman's face, and she's very obviously not Maria Bello.

Continuity mistake: When Evy is trying to seduce Rick, and she finds him asleep in his chair, her hands move from his neck to the back of the chair between shots. (00:17:00)
Chosen answer: For one thing, just because two different years are shown does not mean that a full twelve months passed before they arrived in China. Also, travel to an undeveloped third-world country in the mid 20th century was not like it is today. There were no jet planes, much pre-planning and preparation would have to be done before departure, different modes of transportation would have to be arranged, and there would be many stops, delays, and transfers along the way. This could cumulatively take many months.
