I happened to watch Cecil B. DeMille’s Cleopatra (1934) for the first time today, and I was surprised when, a little more than an hour into the movie, Herod the Great showed up. He says that he has come directly from Rome, and that he is on his way back to his kingdom in Judea, but while he is in Egypt, he has a message for Cleopatra: namely, Octavian wants her to kill Mark Antony.
In the next scene, Herod and Mark Antony share some drinks and some laughs, and then Herod, still laughing, tells Antony that Octavian wants Cleopatra to poison him — a message that Antony himself laughs off, until a later scene in which he discovers that Cleopatra is testing different kinds of poison on her prisoners.
So Herod gets to be friendly with all the major political figures — Octavian, Cleopatra, Mark Antony — while at the same time disturbing the two political figures with whom he shares actual screen time. And you get the impression that he rather likes disturbing his friends, even though they are all discussing serious matters of life and death. The important thing, for Herod, is that he has influential connections, that he can flaunt those influential connections, and that he can keep those influential connections.
I have no idea whether there is any historical basis for these particular scenes. But for what it’s worth, Wikipedia indicates that Herod secured his position as “King of the Jews” with help from both Mark Antony and Cleopatra between 40 and 37 BC, and that, when civil war broke out between Antony and Octavian, Herod switched his allegiance to Octavian in 31 BC. Antony and Cleopatra would go on to die in 30 BC, after losing their war with Octavian, while Herod continued to rule Judea until his own death in 4 BC. Octavian, who went on to become the Emperor Augustus, did not die until AD 14.
Herod, incidentally, is played here by Joseph Schildkraut, who had previously played Judas Iscariot in The King of Kings. Cleopatra, of course, is played by Claudette Colbert, who had previously bathed in asses’ milk as the Roman Empress Poppea in DeMille’s The Sign of the Cross (1932) — and who would soon go on to win an Oscar for starring opposite Clark Gable in the classic screwball comedy It Happened One Night (1934).
