Factual error: Dipple refers to a statue and guesses it to be of Vishu from West Bengal. Truly that art form is still found in present day Bihar, West Bengal, Orissa but it is also found in Southern India. However, the guess is wrong on two accounts, first, Vishnu is a male deity but the statue was that of a female deity. Second, West Bengal came into existence after 1947 (or at least 1902) so there cannot be any concept of West Bengal back in 1820-30. At that point there was only Bengal. (00:25:45)
Factual error: As Ren enters Renautas and meets Emily, the word "Welcome" keeps scrolling in various languages on the screens in the background. Although hardly seen, the Hebrew is wrong, as it is reversed (text from left-to-right, as opposed to right-to-left).
