The safe on top of the stage coach was an original concept thought up by LEGO, but the people working on the actual film liked it so much that they put it in the movie.
The minifigure callout on the box mistakenly shows Kyle, mislabeled "Barret", next to Red Harrington and Jesus when Barret is meant to be in that spot.
This scene was not in the film. Red never owned a stagecoach, though a stagecoach similar to the one featured in the set was in the background in part of the film.
