While we're on the subject of films, check out and critique these Esther films:
The 2006 flick, One Night with the King has utterly fab costumes, but don't count on the historicity. And don't think the strong romantic elements are reality-based. But enjoy it, anyway.
The classic Hollywood film version of the story is the Esther and the King (1960) starring Joan Collins (can you believe it?) and Richard Egan, and directed by Raoul Walsh.
In 1992 Hanna-Barbera produced The Greatest Adventure series, and as part of that set made a 30-minute, fully-animated video, titled Queen Esther. It features the voices of Helen Slater as Queen Esther, Dean Jones as King Ahasuerus, Werner Klemperer as Haman, and Ron Rifkin as Mordecal.
And finally, there's VeggieTales. They made an animated version of the story titled Esther: The Girl Who Became Queen, in which the girl-of-courage shows up as a young green onion. Bring the tissues.
