Plot hole: When Cateleya is in prison she changes into a black cat suit. Where has that come from? Where had she hidden that? She is wearing a very skimpy dress and would not be allowed a handbag or anything.
Plot hole: After January Jones has just told Liam Neeson she doesn't recognise him. Neeson is trying to persuade Herr Strauss and two cops that he really is Dr Martin Harris of Langmore University, and suggests they look for a photo of him online. However, the cop using the computer says that it could take him ages to find a photo of Dr Martin Harris, as "there are more than 40 000 in the USA." This is very true, but as Neeson has already told him not only his name but also his place of work (Langmore university) in reality the cop would have found the photo far more quickly.
Suggested correction: The average cop wouldn't be that quick to realise that he could filter the results. Instead of being a plot hole, this is simply a very human initial response to an initial search result.
Plot hole: When Sam first encounters Dan, the headmaster, Dan reveals that he had to quit his musical career when he impregnated and married a groupie, but that he loved his daughter. Later, Sam runs into Courtney behind a liquor store, and Courtney, who is actually Dan's above-mentioned daughter, discusses her "aggro older brother". If Dan's original error in timing resulted in a daughter, how could she have an older brother?
Plot hole: How did the wolves get across the canyon? Unless they were flying wolves, there's no way they could.
Suggested correction: Just because we don't see how they got across doesn't make it a plot hole. We see next to nothing of the area surrounding the canyon. There could have been a pass or trail in the distance that the wolves used. The characters think they are gradually walking away from where the wolves' den is, so they decide to use a makeshift zipline to get to the other side rather than go back the way they came and risk running into the wolves again.
