Revealing mistake: Avon and Soolin hide from the processing plant guards in an alcove, but Avon's black-booted foot is sticking out in plain sight. Fortunately, the guards don't seem to notice and walk on by anyway.
Continuity mistake: Dayna plants the grenade by the right-hand upright of the ladder. Yet when it detonates you can see the blast is to the left and in front of the guard; presumably to prevent it from going off right in the stuntman's face.
Continuity mistake: When they shoot open the crate containing the gold, Avon is on the left & Keeler on the right. Avon fires and we see the right-hand lock explode, then Keeler shoots and the left-hand lock pops.
It's not every day you can shoot your wife in front of millions of witnesses and get away with it. Klyn, the woman behind the console who sounds the alarm before Avon shoots her, was played by Paul Darrow's real-life wife, Janet Lees Price.
