Continuity mistake: After finding Krebs, Barb handcuffs him, and he always remains cuffed. But after Barb shoots one bodyguard, and he falls out of the window, we see a shot of Krebs looking startled, and his hands are at either side of his legs - he is now uncuffed, although Barb never uncuffed him.
Continuity mistake: When Barb goes to see Big Fatso with the lenses, she's got three ammo belts over her shoulders. The one over her right shoulder is under the two that are over her left shoulder meaning that she'd have to take off the two that are over her left shoulder before being able to take off the one that's over her right shoulder. Then Willis arrives with the Congressionals and he tells her to drop her weapons. When he tells her this, the ammo belts have switched places. The one that was over her right shoulder which used to be under the other two ammo belts is now over the other two ammo belts. Then in the next shot, as she's dropping her weapons, the ammo belts return to where they originally were.
Continuity mistake: When Barb is fighting Kreb's bodyguards, one is walking through the hole in the mattress. In one shot you can see the floor of the room that the bodyguard is approaching - it is totally covered in small feathers from the mattress. But in the next shot as he enters the room, the floor is now free from feathers.
Revealing mistake: When the soldier is asking for a dance from Barb, Curly says to Barb "Come on Pam."
Continuity mistake: When Barb is fighting Kreb's bodyguards, as she fights with the second one, she boots him to the floor, and them stands on his crotch. The bodyguard has blue suspenders on. In one shot one of his suspenders is unclipped and is lying across his body. In the next shot the suspender is now neatly clipped back onto his trousers. In addition the gray jacket he wears also changes position.
Continuity mistake: In Barb's war flashback we see her in a military uniform next to a helicopter that's about to take off. In some shots her left hand is on her helmet but in other shots it's at her side.
