Continuity mistake: When Larry first starts playing with Rex there is a sheet under Rex by his feet which is folded up neatly, but two seconds later the sheet is now disheveled and partially on the floor. Then within seconds this sheet is now still disheveled but completely on the edge of the display. (00:10:00)
Continuity mistake: When Sacagawea wakes up from her shipping container, the styrofoam popcorn comes out everywhere as she gets up. But moments before when it shows her being put into the box, there is no styrofoam, rather she's packed in with hay.
Factual error: When Larry and Amelia enter the VJ day at Times Square photo (AKA kissing sailor) we get to see what was in front of the sailor and nurse but Alfred Eisenstaedt, the photographer who took the picture, is nowhere to be seen.
Factual error: The billboards behind the kissing sailor and nurse photograph don't match the ones from the real photo.
Factual error: Whenever Ivan the Terrible summons his guards he says "streltsy" which actually translates to "archers".
Suggested correction: Streltsy translates to "shooter", but they were an elite unit of the military and part of their duties included being personal bodyguards of the tsar.
Factual error: The combination is set to a high-decimal count of Pi (3.14159265), but pi wasn't calculated to that precision until the 15th century. The Egyptians did have a rough estimate of pi, but not that good.
