Some of my kids are sick, so for our Sunday night family worship we are watching One Night with the King, a terrific movie that recreates the story of Esther from the Old Testament book. It is very faithful to the biblical story, with just a few minor exceptions, and sometimes even the "embellishments" are a blessing, like the subplot of Xerxes' and Esther's marital problems, which illustrates the consequences of wrongful judging (1 Cor. 4:5-6) and bad communication (Prov. 18:13, 17).
To me the very best part of the movie is the scene in the marketplace where Naaman demands that Mordecai bow to him... what a great example of standing for the truth (literally!), and some great comic relief thrown in too.
I highly recommended this movie for any age, though you may have to talk to the youngest childern about some of the adult themes.
