These continuity photos show the cave, the men’s costumes (including the blood on Gus’s boot), and the men in the cave—all aspects referred to in the adjacent shooting schedule.
While a scene may take a few minutes in the finished film, it may take several days of filming that scene in order to get the director’s desired footage. It is critical that each actor’s costume remain the same so that shots taken from different angles on different days can be edited together to look as though they flowed in real time. For instance during filming, a bandana tied on the left one day and tied on the right the next might seem to fly back and forth on an actor’s neck after the film has been edited to include images of him blended from different days of filming. The continuity Polaroids serve as documentation for each day’s costume for each actor.
