Continuity mistake: When the team is escaping with Al, BA swipes a truck. After loading everyone in, he puts a pin in to hold the gate on the driver's side. When they meet up with Face & Murdock at the helicopter, Hannibal jumps out, pulls one pin from the passenger's side, and the gate swings down.
Other mistake: When the two women first see the bus pull up and get on, the next scene we see when it picks up BA is the same video footage as when it arrived to pick them up. You can also see the same pink neon lights in the reflection of the bus and bus stop before it quickly cuts away. (00:02:50 - 00:04:20)
Continuity mistake: The chain for the air horn is being pulled by Hannibal's right hand. Suggesting it's mounted over the driver's right side, in the middle of the cab. A second later, the chain is seen swinging at the top right of the shot on Hannibal. (00:20:15)
