Visible crew/equipment: In the car chase scene on Vilena, there is a point where Sandra's truck is headed from screen left to right, partially towards the camera. The windshield reflects the overcast sky interrupted by the reflection of a boom crane. (00:39:35)
Character mistake: Tool neglects to dress Barney's tattoo after he completes it. Not something a professional tattoo artist would neglect to do, especially when he is tattooing a friend.
Suggested correction: Tool states that it's taken him several months to do the logo tattoo. It's also implied that he has done the rest of Barney's tattoo's. Barney, being the tough man he is, could have simply said in the past not to bother with dressing it and Tool has done as told against his better judgement.
