Continuity mistake: In the scene explaining the history of the missing jade elephants, they are described as being given to ambassadors by the emperor Zhu Di of China when the Forbidden City (in China) was first opened to foreigners in 1421. When the elephants are all brought together, the representative Daichi Yoshida from the Japanese embassy comes to pick them up, describing them as "a priceless piece of our history."
Factual error: When Neil figures out how much the bank robbers took they say that each of the 4 robbers are carrying 2 briefcases which means they have 8 in total. If you multiply the $960,000 in each case by 8 you get $7,680,000 which is $520,000 off the $8,200,000 the robbers supposedly got away with, not the $1,500,000 Peter says the difference is. (00:41:45)
