Continuity mistake: Just after they rob the gas station they do a turn in the road to avoid the cops. If you look you can see skid marks doing the exact same turn in the same place, revealing they are from previous takes.
Continuity mistake: When T is saying to Nick what he would have done in Nick's situation, he has grass in his hair that is constantly moving.
Continuity mistake: When being chased, the 4x4 gets damaged down one side. When leaving from the heist, it is fine.
Revealing mistake: Nick sprays T.'s eyes with mace, but a few seconds later, when they approach a red light at full speed, T. opens his eyes wide and they are not even red. (00:13:35)
Continuity mistake: When Nick gets back to the hotel room the robbers have left T. sitting on a chair, precariously balanced on the railing of the balcony, held back only by a bedsheet whose other end is stuck between the balcony doors. Only a small tip of the bedsheet sticks out right next to the spherical doorknob, but a few shots later there is a close-up where a larger tip sticks out and the doorknob is flat. (01:15:20 - 01:16:25)
Continuity mistake: When Nick and T. chase the two robbers to get their money back there are two tidy wads of notes stuck under the right sun visor. At a wider camera angle the money isn't there, but when it cuts back there are even three wads, and the middle one is rather crumpled. (01:17:45)
