Continuity mistake: This has the old T.V. show style "it was 6 a.m. on January 7th we ... " beginnings to the scenes. Pay attention to those times and dates. They're not even close to being in sequence. I mean days, not just times.
Other mistake: When Friday & Streibeck are driving the armoured car towards the milk factory for the raid, there is already milk streaming down from the back of the armoured car even though they haven't hit the factory yet.
Continuity mistake: When their car blows up, look in the background and you can see Friday practically kneeling on the ground, and Streebeck falls over completely. Within two seconds (and a couple of cuts) they're both standing up, fully alert with their guns out - Friday might just have managed it at a push, but Streebeck went from face down on the pavement to upright far too quickly.
Continuity mistake: During the chase with Muzz, a yellow hatchback that Streebeck steers around to avoid appears from nowhere. As he's passing it, there is a long enough close up to show Friday and Streebeck passing the yellow car, but it doesn't show up. Only in the long shots is it there.
Continuity mistake: When they are at the p.a.g.a.n. convention, Sgt. Friday's wig is completely dry seconds after he gets out of the water filled pit.
