Continuity mistake: There's Fall foliage at the beginning of the movie and when Bokky [Bill Paxton] and Pat [Mark Wahlberg] are leaving the camp grounds but, after they drive away, the foliage is Summer-like (and varies thereafter). (00:19:50)
Plot hole: Marcus told Melena he lived in New Mexico with his parents until he was 5 years old: "My dad died in a car accident when I was five... and my mom got caught smuggling people into the country, so she got 10 years [in prison]." Even though Marcus did not know at the time the real reason his mother was in prison, the murder must have occurred in New Mexico, so it doesn't make sense that she would be serving time in a New York prison.
