When Ava tries to escape from the zip tie in the Gremlin, she rips the grab bar loose but that won't stretch the zip tie. At ~30:10 it is loose enough for her to get her hands out. Had it been that loose all along, she would not have needed to rip the grab bar off.
The character "Boon" draws his revolver and pulls the hammer back. He pulls the trigger only for the gun to not fire. He then explains that you have to let the gun rest on an empty chamber to prevent accidents (something an experienced shooter wouldn't be worried about by the way).
The problem is that double action revolvers will rotate the cylinder when you pull the hammer back, thus advancing to the NEXT chamber. This means that either Boon was wrong about resting his gun on an empty chamber or, even worse, had TWO empty chambers in his gun.
