Over the years, there have been many movies made off Bible stories. Most of them are terrible.
The terrible movies run the gamut from low-budget, overacted Bible School schlock, to trashy, intentionally sacrilegious made-for-tv schlock. (Does anyone remember the made-for-tv "Samson and Delilah" miniseries? No? You're lucky.)
Even the big budget movies haven't fared much better. "The Ten Commandments" is a classic, but that movie's 40 years old, and the acting is terrible. (It probably doesn't help that I can't watch it without yelling, "The golden calf is people! It's people!") Plus, Charlton Heston kind of ruined everything by just becoming a crazy old guy who was way too in love with his guns.
Then we had "The Passion" which was awesome, but also kind of ruined when we found out that, true to what everyone was saying, Mel Gibson really is a crazy racist who is way too in love with graphic depictions of torture.
So, that leaves the best Bible movie in 20 years to be "Prince of Egypt", and that was a cartoon (great songs, though).
What we need is a big, sprawling, epic movie (or series of movies) based on a story that's full of action, betrayal, torn loyalties, all that jazz. If movies like "Troy" and "300" can be wildly successful, there's no reason that 1 Samuel can't be the next period epic blockbuster.
Being the awesome movie producer I am, I've even figured out the casting.
