Cecil B. DeMille’s 1923 The Ten Commandments is quite the landmark for the director. While not technically his first historical epic (that was the 1916 Joan the Woman), it was his first Biblical pageant and his first financially successful epic.

But it is also DeMille in the midst of his transition from the lively, witty director of sex farces and sexy romantic comedies with jazz-age sensibilities to the humorless director of white elephant epics, where he’s simultaneously become both more lurid and more pious, reveling in the sins of his characters and then punishing their excess to provide a lesson for us all.
DeMille spends a mere 45 minutes (of the film’s 135-minute running time) in ancient Egypt with Moses the Law Giver, who has already unleashed nine plagues as the film opens and exits after destroying the tablets in face of the blasphemy of his followers. For the rest, we dissolve to the present (circa early 1920s) to find a white-haired old mother reads from the good book to her two sons, one lost in the glory of the lesson (the all-American Richard Dix as John, a humble carpenter, of course), the other a restless, modern and cynical jazz-age kid (Rod La Rocque as Dan), bored with all “that bunk” of the Bible lessons. “No one believes in these commandment things anymore,” he sneers to his shocked old mother, and he marries another modern girl (Leatrice Joy as Mary, naturally) with a pledge to “live our life in our own heathen way.”
There’s plenty of decadence in both sides of this split identity production, from the orgiastic sin spectacle of hysterical partying and blaspheming with a false idol of the ancient section to Dan systematically breaking all ten commandments in his rapid rise to wealth (and, naturally, his precipitous fall) as a corrupt contractor whose reckoning comes when he builds a church with rotten concrete.
But DeMille’s trademark sensibility (revel in sin for the spectacle, then punish the transgressors for a moral lesson) aside, they two sections illustrate what the director gave up in his transformation into epic moviemaker. The section with Moses in the Holy Land is, dramatically speaking, little more than an epic version of a biblical pageant. Stodgy and stiff and as old fashioned as an early D.W. Griffith spectacle, it’s a series of tableaux with old man Moses (Theodore Roberts), in flowing white hair and madman beard, doing a lot of posing and pointing as he threatens the Pharaoh, leads his people into the desert and brings the wrath of God upon the Egyptian slavers and soldiers. But DeMille is a showman and he makes a show of this otherwise moving illustrations of bible stories with stunning special effects: the parting of the Red Sea (using the very same techniques as he did thirty years later in his 1956 edition), the wall of fire, the great balls of fire pyrotechnics for the will of God as he delivers the commandments to Moses.
