 In the original conception, three men were seen talking and    bathing in red mud. They are startled when Caligula first appears    in the hallway outside Tiberiuss pool. As Caligula walks down the    hall, we see fragments of tortures that occur on the other side of    the curtain. In the movie, the scene with the three men was moved    *after* Nervas death, and entirely new dialogue was dubbed over    the shot, making it appear that the men are discussing Nervas    recent death and Tiberiuss imminent death. They appear to be    startled, then there is a cut to Caligula across the palace,    fantasizing about torture, intercut with the fragments of tortures    that were meant to be about 15 minutes earlier in the film.
