Character mistake: Theo lights a cigarette after getting a fresh change of clothes at the "safe house" he steps outside and lights up a cigarette. But if you look closely, he accidentally lights the cigarette up backwards, and he even takes a few drags off it. (00:34:00)
Continuity mistake: As Theo is sitting down at his desk, the camera comes up from behind the woman across from him, who has small knick knacks and figurines covering her desk. The shot zooms in on Theo and then switches to the crying woman. When the shot changes, notice the "fat-baby" figurine suddenly switches with two-smaller animal figurines. It's hard to tell what they are, but it's easy to see they've been switched with the baby.
Continuity mistake: When the windscreen is shot at, it begins to crack across, showing it's laminated as you'd expect, then in the next shot it shatters as though it is toughened glass. Laminated glass doesn't shatter into hundreds of pieces.
Continuity mistake: When the man leaves the greyhound track and runs for the bus, that type of bus is an old metrobus, but the inside of the bus he jumps on at the time is a brand new (at the time) Dennis president bus.
