During the song "Playing with the Big Boys" , a cobra is seen swallowing two snakes.
Many of the slaves suffering is intense.
Moses has a dream that shows him and other characters come to life as painted reliefs (wall engravings). In it, we see him being chased by soldiers, as well as those soldiers stealing crying infants from their mothers. We later see the final (non-moving) relief that depicts infants being dropped into a river where they sink down toward the waiting, open jaws of two crocodiles.
Images of the plagues striking Egypt include people having large boils on their skin and cattle dying.
A prolonged scene where the plague (in the form of a ghostly, whitish vapor) comes from a portal in the sky, wisps in and around the Egyptian and Hebrew homes, and kills people, including children, that were the first born (we hear the last gasp from several victims and see a young arm fall lifelessly to the ground).
There is a lot of destruction and visible suffering.
The most intense songs are "Deliver Us" and "The Plagues".
Overall the entire film is very emotional in its approach to its themes. Particularly in how much focus is put on the relationship between Rameses and Moses
