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: As the chopper that is piloted by Murdock comes down over and behind the thug's car, you can see the the man in the left seat has a ball cap and brown jacket on, but the man in the right seat has a dark sweater, shades, and headphones on. In the close up, it's Murdock and the Professor.
