Factual error: The head of Harvard's office is described as one hundred years older than the country dating it as 1676. When the twins leave they break a doorknob and it is given back with the line "here's your 335 year old doorknob" which would place the action in 2011. In fact it's 2004/5.
Revealing mistake: When Mark gets a nasty note from a Harvard classmate and storms out of a computer class, a directory sign saying "USC College of Letters, Arts & Sciences" (ie. University of Southern California, not Harvard) can easily be seen on the hallway wall through the door as he opens it and walks out.
Audio problem: After the boat race when one of the Winklevoss twins (hard to distinguish which one) says "Let's gut the fricking nerd", you can see him mouth "fucking nerd." "Fricking" also sounds extremely dubbed in.
Answer: No, earlier when it came up in the lawyers office, Eduardo thought it came from Mark, but the lawyer stepped in and said they were able to find it themselves. Sean really had no idea what he was talking about, but didn't use it against him.
