Character mistake: Upon finding the Spanish flu virus missing, Hardison freaks out about it killing 50m people 100 years ago, saying it would be even more deadly today due to the higher population. There's no reason to think so - the death toll in 1918 was massively exacerbated by the aftermath of WWI. Not to mention today we have vaccines, plus most deaths then were actually caused by bacterial pneumonia, which today is easily treated with antibiotics.

Audio problem: When Hardison is talking to Carrey, just after he names his price ("30%"), there is a shot from a strange angle in which we hear Hardison talk while his mouth doesn't move at all.
