In the scene of La Batalla de Tacines, one of the cannon blasts managed to destroy part of the lens of one of the cameras. The shot in which the cannon is seen and then a mess of broken glass in the lower right of the frame after the blasting were kept in the final recording.
In the scene where Camilo Torres and Jorge Tadeo Lozano were shot, there are some thin cables (which trigger the blood Squibs) coming out of the waist of the actors and down the scaffold, where they are located.
