Plot hole: In Cayman, a drugged Avery passes out on the bed, fully clothed. Abby is in the kitchen, carrying the Mafia files. The bedroom is in the background, only now Avery is under the covers and undressed. He was drugged and too heavy for Abby to move and undress alone and have enough time to also transport files, copy them, and return everything to the bungalow before Avery awoke. Avery would also know he passed out atop the bed and not under the covers.
Suggested correction: When he falls, his head is about 3 feet from the pillow, where it is later in the background. Abby would only need to drag him up the bed. Pretty easy even for someone with Abby's build. Avery's shirt is fully unbuttoned when he falls backwards onto the bed, so removing it would be very simple. Then all she needed to do was drag the cover out from under him and put it over. She could probably do all that in 2 minutes. Also, Avery wouldn't have been suspicious, only confused.
Character mistake: At the end, when Mitch tells Agent Tarrance that the government can convict the law firm on mail fraud and racketeering, he says he got the idea while he was studying for the bar exam. He actually got the idea from a client earlier in the film when the client was complaining about being over-billed and tells Mitch that every time a bill is mailed through USPS, the firm is committing mail fraud which is a federal offense, punishable by fines and prison.
Suggested correction: This is not wholly correct. Mulholland (the client) planted the seed in Mitch's head, but Mitch realised instantly that it was a federal offense, presumably because he had studied it.
